Frequently Asked Questions
Does this solar inverter support 48V batteries?
Yes. The product uses a nominal 48VDC battery system. Battery operating voltage, charging requirements and communication compatibility must match the selected inverter model.
Is WiFi monitoring included as standard?
WiFi monitoring is optional and requires the compatible accessory.
Can this inverter be installed outdoors?
The specified protection rating is IP21. It is intended for installation in an appropriate protected indoor environment.
Can it communicate with LiFePO4 batteries?
The specifications list RS485 lithium battery communication. Compatibility depends on the battery's supported protocol and inverter configuration.
Is maximum PV array power the same as inverter output power?
No. Maximum PV array power describes the permitted solar array configuration, while rated output power describes the inverter's continuous AC output capability. Both must be checked separately when selecting a model.
