The documented bakery installation in Ruhpolding, Bavaria, Germany, shows the production impact of oven-driven power peaks. At a separate bakery with 380 kW of preheating demand against a 300 kW grid-import limit<\/a><\/strong>, MegSolid ESSA0100B-0215<\/a><\/strong> directly addresses the 80 kW shortfall with 100 kW rated output, 215.04 kWh nominal storage and integrated C&I energy storage<\/a><\/strong>.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

Keep the First Baking Batch on Schedule With MegSolid ESSA0100B-0215<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t

The first batch has to wait until the ovens reach operating temperature. Staggered preheating keeps import below the grid limit but delays baking and packing. Upgrading the utility connection may take longer than the production schedule allows. The storage system must cover the peak and preserve enough energy for the next batch.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

In Ruhpolding, Bavaria, Germany, an industrial bakery project<\/a> addressed daily electricity peaks of 100\u2013150 kW caused by ovens and other equipment. Dumarey\u2019s installed system kept grid demand at 100 kW while the ovens ran together, allowing production to continue without upgrading the connection. The Ruhpolding installation is Dumarey\u2019s project, not a MegSolid installation.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

The 80 kW Power-Class Decision<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t

MegSolid ESSA0100B-0215 is the best-fit product for the bakery's defined 80 kW power deficit.<\/strong> Its 100 kW rated PCS provides 20 kW of nameplate headroom, while the 215.04 kWh nominal LFP battery, integrated EMS and built-in isolation transformer put the key storage equipment into one cabinet. The 80 kW gap does not require the bakery to order a separate 150 kW PCS just to start the ovens.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

The 100 kW rating covers the initial 80 kW power requirement. The cabinet must also deliver both batches at the accepted AC energy boundary, with charging controlled beneath the grid limit.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

Measure the Oven Power That Production Cannot Reschedule<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t

Oven nameplates do not establish the required battery discharge. Record total site active power during the preheat period, identify which ovens must operate simultaneously, and compare the measured demand with the grid-import ceiling established for the connection.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

The bakery operates with a 300 kW import ceiling and reaches 380 kW when the ovens preheat together. Each of the two preheat events lasts 45 minutes. Between them, production runs for 45 minutes at a site load of 260 kW.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

The continuous battery-power requirement is 380 \u2212 300 = 80 kW AC<\/strong>. Each preheat event needs 80 \u00d7 45\/60 = 60 kWh AC<\/strong> if the deficit remains at 80 kW for the full 45 minutes.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

One 50 kW ESSA leaves 30 kW of the 80 kW deficit uncovered at rated output. The 100 kW ESSA0100B-0215 instead has 20 kW of rated-power headroom above the initial duty; live BMS, PCS and environmental limits still govern available output.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

The 80 kW and 60 kWh results define the duty for each preheat. Verify it against the site load profile and measured AC delivery across the full production cycle, not equipment nameplates.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

Specify MegSolid ESSA0100B-0215 for the bakery's 80 kW preheating duty.<\/strong> Its 100 kW rated AC output provides 20 kW of nameplate headroom, and its integrated LFP battery, PCS, EMS and isolation transformer consolidate the principal storage equipment in one cabinet. The first-batch power requirement does not call for a larger conversion stage.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

The 215.04 kWh nameplate identifies the battery class. Usable AC energy over the approved SOC window determines whether it can complete both batches. The site-level BESS design<\/a><\/strong> connects that duty to protection and the approved electrical arrangement.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

The integrated 100 kW cabinet covers this power duty; peak power alone does not justify a larger PCS or container. The built-in isolation transformer is part of the supplied package; site switchgear, PCC metering, cabling and commissioning remain in the electrical scope.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

Keep the ESSA0100B-0215 recommendation tied to the entire production morning, not only the first oven cycle.<\/strong> Each 45-minute event requires 60 kWh AC at the 80 kW deficit, so two batches need 120 kWh of delivered AC energy before intermediate charging. An undersized energy window would preserve the first batch but delay the second even when the PCS power rating is sufficient.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

Between batches, site demand falls to 260 kW, leaving 300 \u2212 260 = 40 kW of theoretical charging headroom<\/strong>. Over 45 minutes, that allows at most 40 \u00d7 45\/60 = 30 kWh of AC charging input<\/strong> at the defined grid boundary. That is a ceiling before any control margin, fluctuations, equipment restrictions or conversion losses\u2014not a 40 kW fixed charging instruction or 30 kWh of energy that the battery can later deliver.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

Starting Energy Must Exceed the 90 kWh Lower Bound<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t

The 90 kWh figure is a loss-free lower bound, not the required starting SOC or an acceptance value.<\/strong> At the agreed AC delivery boundary, define E\u2080<\/em> as the AC energy deliverable from the starting SOC down to the approved minimum SOC, and E\u1d63<\/em> as the additional AC energy recoverable from charging between batches.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

The two-cycle requirement is E\u2080 + E\u1d63 \u2265 120 kWh AC<\/strong>, plus any separately specified concurrent duty. The positive grid-import margin cuts charging input below 30 kWh, and conversion losses reduce recoverable discharge energy further. E\u2080 must exceed 90 kWh AC<\/strong> for the stated duty.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

If a reserve is required, exclude it when measuring E\u2080; do not count the reserve as usable production energy.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

Verify the Two-Batch Duty Before Ordering<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t

MegSolid ESSA0100B-0215 combines the required 100 kW power class with 215.04 kWh nominal storage in one product. That capacity provides the basis for assessing both oven cycles without moving directly to a larger equipment class. Purchase acceptance is the measured usable AC energy over the agreed SOC window<\/strong>, not an assumed conversion of nameplate kWh into runtime. IEC TS 62933-2-2:2022<\/a> addresses application duty cycles and performance testing; the project test must reproduce the 60 kWh discharge, limited charging interval and second 60 kWh discharge against agreed criteria.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

The purchasing route is one ESSA0100B-0215, with the complete two-batch duty written into acceptance. Its tested AC output, available energy, starting SOC and site temperature must sustain the production schedule. That test determines whether the specified single cabinet can serve production without increasing equipment size on an unverified energy assumption.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

Keep both preheating batches on schedule.<\/strong> MegSolid can review the 80 kW duty, two 45-minute heating periods and intervening recharge window to confirm whether one ESSA0100B-0215 meets the complete cycle.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

A fixed 40 kW charging command works only while the bakery's other loads remain at 260 kW. If process demand rises to 280 kW, that same command would raise grid import to 320 kW and breach the stated 300 kW ceiling.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

During a steady 260 kW interval, margin-capped input is at most 0.75 \u00d7 max(0, 40 \u2212 M) kWh<\/strong> over 45 minutes; equipment limits or rising load can reduce it further.

MegSolid ESSA0100B-0215 brings the EMS and published RS485\/TCP\/IP communications into the cabinet rather than requiring a separately selected core storage controller. At the bakery, the measured site load sets charging availability; the next preheat takes priority when demand rises.

\n\t\t\t\t\t

ESSA coordinates the power and energy duty in one cabinet:<\/strong> at a steady 260 kW site load, the theoretical 40 kW charging window is available; if the load rises to 280 kW, headroom falls to 20 kW before the project margin. The EMS dispatch must follow the changing meter reading so charging does not become a new reason to stop the ovens. Contractual averaged demand and instantaneous connection limits require separate control settings where the utility agreement distinguishes them.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

MegSolid ESSA0100B-0215 gives a 400 V bakery an integrated 100 kW storage interface with a 144 A rated AC current and built-in isolation transformer.<\/strong> The specified voltage matches the initial low-voltage equipment class, allowing the project to focus its connection study on the actual feeder, switchboard, protection and import-meter boundary.

\n\t\t\t\t\t

Check Energon Active Power Before the 120 kW Upgrade<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t

\u0627\u0644\u0640 Energon 261 liquid-cooled cabinet<\/a><\/strong> provides 261.24 kWh nominal energy and a 125 kVA rating. At unity power factor, 125 kVA corresponds to 125 kW in the simple apparent-to-active power calculation; at 0.95 power factor it corresponds to 118.75 kW, below the bakery's new 120 kW requirement.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

The arithmetic threshold is 120\/125 = 0.96 power factor<\/strong>, before thermal derating and model-specific active-power limits. Use Energon for the expanded duty only when its confirmed active output and usable energy meet the complete cycle.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

When the 150 kW PCS Becomes Necessary<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t

MegSolid's MEGA0150TS PCS<\/a><\/strong> delivers a published 150 kW rated conversion class: 30 kW of nameplate headroom<\/strong> above the revised 120 kW gap. It is the clear higher-power PCS route when the Energon cabinet does not meet the confirmed active-power duty. The separate PCS still needs a compatible battery, DC protection and controls. Compare that package with the integrated cabinet on total scope and accepted AC energy.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

\u0627\u0644\u0640 MegSolid C&I portfolio<\/a><\/strong> also includes ESSC0500B-1075, with 500 kW rated AC power and 1.0752 MWh nominal energy. The 500 kW container belongs to a different equipment class.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

The bakery retains cabinet-class equipment until its measured peak gap, cumulative AC energy or project installation scope warrants a container.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

Confirm the expansion path before upgrading equipment.<\/strong> MegSolid can compare the ESSA cabinet, Energon power class and 150 kW MEGA PCS route against the revised oven schedule and the bakery's electrical connection.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

Prove Both Preheating Cycles Before the Cabinet Enters Production<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t

Accept the MegSolid ESSA0100B-0215 against the bakery's actual production result: two 45-minute oven-preheating events completed while grid import remains within the approved operating limit.<\/strong> One successful discharge or a communication-only SAT cannot establish that result. The full sequence must test the 80 kW power duty, intervening charging and remaining usable energy together.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

IEC 62933-2-1:2017<\/a> defines system performance parameters and test methods, allowing the bakery to specify the AC power and energy measurement boundary. IEC TS 62933-2-2:2022<\/a> addresses application-specific performance testing and duty cycles; the bakery should use its two-discharge, one-recharge production sequence as the agreed acceptance duty. The project establishes the pass criteria rather than treating a standard citation as an automatic product-performance guarantee.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

The usable-energy boundary must be measured at the agreed AC point, accounting for the test's approved treatment of conversion and auxiliary losses.

\n\t\t\t\t\t

Accept MegSolid ESSA0100B-0215 only after it demonstrates 80 kW output, the complete two-batch AC-energy duty and PCC-controlled charging.<\/strong> The acceptance record must show that preheating stays on schedule and grid import remains within the agreed limit.
