When a project owner buys the battery system directly, appoints an EPC to install it and asks the equipment supplier to commission it, the BESS EPC scope is commercially complete only when every interface has an owner. MegSolid can supply the integrated BESS, controlled interface documents and agreed factory and commissioning support; the EPC still needs a signed boundary for civil works, switchgear, cabling, site controls and energization. The overall duty remains anchored in the C&I-battery-energie-opbergstelselontwerp<\/a><\/strong>, while the package split follows the project-specific BESS equipment and balance-of-plant boundary<\/a><\/strong> and the approved 400 V-skakelbordverbinding<\/a><\/strong>.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

The usual failure is a small task left out of both contracts. A cabinet arrives, but the purchase order does not name the party responsible for unloading. The EPC installs the AC cables, but no document states who approves terminal torque before first energization. A site test then fails, and one warranty covers equipment defects while the other covers workmanship. The owner is left coordinating evidence, corrective work and a second test while the commercial operation date keeps moving.<\/p>\t\t\t\t<\/div>\n\t\t\t\t
