Axpert inverter with solar working


Recommended Posts

Hi, can you pls explain how the Axpert works with solar panels connected, I would like to know if the panels always charge the battery and the inverter will convert the power in the battery to AC and if the batteries are full do you covert power from the panels or do the system always convert from the batteries. Hope it makes sense. Thanks

There are many models. Some models (usually described as having 145 V max PV) directly connect the Solar Charge Controller (SCC) output to the battery. So in a sense, it's always charging the battery. But if there is a load on the battery, the load will use the PV power first.

Other models (usually described as 450 V or 500 V max PV) boost the PV voltage to the "bus" voltage (400-500 V). They can still charge the battery, but it's via a different route.

and the inverter will convert the power in the battery to AC

There are two main modes: battery and bypass (the Axpert  Kings have a third mode, line mode). In battery mode, the inverter converts battery or PV power to AC.

In bypass mode, AC-in powers the loads, and the battery is charged (if needed) from PV and/or from AC-in.

In the Axpert King's line mode, it has an extra power converter that allows it to blend AC-in power with battery and/or PV power to power the loads.

The models with 450 V or 500 V max PV can sometimes blend AC-in and PV power.

With all models, it's possible to use PV power when the battery is full. Some models can even power loads without a battery present.
