VEVOR Hybrid Solar Inverter, 3500W, All in One Pure Sine Wave Power Inverter Charger, 24V DC to Single-Phase 220/230V AC, with 100A MPPT Solar Controller, for Off-Grid System Lead Acid Lithium Battery

The AC output operates at either 50 Hz or 60 Hz (with a rated voltage of 220V/230V AC), which automatically matches your utility grid frequency in grid-tie bypass mode or can be manually selected via program settings (Program 09) between 50 Hz and 60 Hz in off-grid battery inverter mode.

Yes, this hybrid solar inverter features a built-in automatic transfer function. In the event of a utility power outage, it automatically switches to battery/inverter power, and when utility power is restored, it automatically switches back to grid power. The transfer time is approximately 10 ms, helping ensure uninterrupted operation for most connected devices.

Sure. However, it’s best to use two batteries that are the same age, brand, and specifications. Ideally, they should be 24V lithium iron phosphate batteries. If this answer does not resolve your issue, please contact us again for assistance.

It needs to be connected to a 24V battery. If you have two 12V batteries, you can also connect them in series to form a 24V battery.

This can be installed downstream from panel solar controllers.
