Common Questions
What inverter brands are compatible?
Our BMS supports CAN/RS485 communication with Deye, Growatt, Victron, Luxpower, Goodwe, SMA, and many others. We also offer our own matched YUEGU inverters.
What is the standard warranty?
We provide a 10-Year Warranty or 6000 Cycles (whichever comes first) on our LiFePO4 battery modules. Panel warranties are typically 25 years.
Do you provide mounting structures?
Yes. For "Full System Solutions," we calculate and supply roof mounting rails, clamps, and PV cables based on your panel count.
What is the lead time?
Standard batteries ship in 7-10 days. Full custom system packages typically require 15-20 days for consolidation.
