Questions Before Quotation
What are the rated capacities of this 125 kW 241 kWh BESS?
The configured package combines a 107.25 kWp photovoltaic array, 125 kW PCS output and a 241 kWh LFP battery cabinet rated at 768 V and 314 Ah.
What is integrated inside the outdoor energy storage cabinet?
The cabinet integrates the battery cluster, BMS, battery high-voltage box, 125 kW MPPT, 125 kW PCS with isolation transformer, local EMS, industrial air conditioning, insulation and fire-fighting equipment.
Can the system support motor or compressor starting loads?
The workbook specifies a PCS with isolation transformer and strong capability for motor and compressor peaking loads. Final load compatibility must be checked against the project load list and starting-current profile.
Can this BESS work with the grid and a diesel generator?
The configured AC distribution box is designed to manage city power, diesel generator, solar power and output loads. The final operating logic and switching arrangement are set during project engineering.
What cabinet protection and cooling are included?
The outdoor cabinet uses air-duct cooling, cooling fans and an industrial refrigeration air conditioner. It also includes 50 mm A1 fireproof rock wool, thermal insulation and fire-fighting equipment.
Can this system be integrated with an existing solar installation?
A retrofit may be possible after checking the existing array voltage, string layout, grid connection, generator arrangement and load profile against the 125 kW MPPT and PCS configuration.
What information is needed for an engineering quotation?
Provide the project location, load list and starting-current data, required backup duration, grid and generator conditions, installation type and available site drawings so the system can be engineered correctly.
