Fronius Primo 3.8kW Inverter FRO-P-3.8-1-208-240
Great service from A1 SolarStore. Unfortunately, the inverter was defective out of the box. Hardware error 407. Fronius tech support is very good. Awaiting the replacement.

Fronius Primo 3.8kW Inverter 3.8-1
The inverter itself is great, but it’s suitable only for very small installations. Well, a 5kW one actually is fine. Too bad it’s grid -tie, i wanted to use it for my van(

Fronius Primo GEN24 10kW Inverter FRO-P24-10.0-208-240
I bought Fronius Primo 10kW for a system consisting of 27 modules 370W each. So far so good. A1 Solar had the lowest price, but their standards were up to the expectations. Can recommend both the inverter and the store

I’m looking for an inverter that can cope with a high altitude, what about this one?
A1 SolarStore
This Fronius Primo Inverter can operate normally at heights of up to 13,120 ft.

Is it too weak to handle 5 kw of panels?
A1 SolarStore
Recommended PV power for this model is 3 to 6 kWp, so it should be alright.
