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

Can you send it to Montreal?
A1 SolarStore
Not at the moment. We might extend delivery to Canada in the future.

does it keep working when grid goes down?
A1 SolarStore
No. All grid-tie inverters are required to shut down during power outages for safety reasons.

what is MPPT?
A1 SolarStore
Maximum Power Point Tracker. Basically, it serves to balance voltage and current in the system for maximum production.
