EG4 — Common Questions
What EG4 inverters and batteries do you service?
We service EG4 6000XP, 3000EHV-48V, 12000XP, ChargVerter, and EG4-6000XP all-in-one inverters, as well as EG4 WallMount Lithium, LifePower4, and 48V LiFePO4 battery systems. We also service EG4 PowerPro and EG4 18kPV inverters.
Can you service an EG4 system I installed myself?
Yes. We service EG4 systems regardless of who installed them, including DIY installations. We can diagnose configuration issues, update firmware, check wiring, and verify the system is operating safely and efficiently.
My EG4 inverter is showing a fault code — what does it mean?
EG4 inverters display fault codes for issues including battery communication errors, overtemperature, grid faults, BMS protection trips, and MPPT faults. We diagnose the root cause on-site using ICC Solar software and determine whether the fix is a configuration change, firmware update, or hardware replacement.
Can you add more EG4 batteries to my existing system?
Yes. We can expand your EG4 battery bank by adding additional WallMount Lithium or LifePower4 units. We handle all wiring, BMS configuration, and system commissioning to ensure the expanded bank operates correctly.
Do you service EG4 off-grid systems in foothill and mountain communities?
Yes. We service EG4 off-grid and hybrid systems in foothill and mountain communities throughout Fresno County and Madera County, including Prather, Auberry, Tollhouse, Shaver Lake, Oakhurst, and North Fork.
