1. Can it operate without batteries?

Yes, it supports battery-free operation.

In this mode, the inverter uses the PV input directly to power the loads. As long as sufficient solar energy is available, the loads can be supplied directly.

However, we recommend carefully evaluating the power stability and load requirements during system planning to ensure reliable performance.

2. Does the inverter support parallel operation?

No, parallel operation is not supported.

This model is designed for standalone use and cannot be connected in parallel with other units.

3. Does the inverter support remote monitoring?

Yes, it does.

With built-in WiFi or optional RS485 modules, you can monitor your system anytime via mobile app or PC.
