I am looking at getting a grid connected solar system installed on my home. For the inverter I am tossing up between a Fronius and SMA, but it might come down to what an installer might be able to do a better deal on. For someone who is keen on DIY interfacing to monitor power generation is there a logical choice between these two inverters?

Fronius is the best inverter for long term use because it is easy and quick to repair and it will be supported in 15-20 years time.

it has the widest working voltage range and it does the 30% overpanel thing standing on its head.

I wouldn't interface with the inverter the OEM stuff is expensive and restrictive. The modbus protocol is open and standardised so it can be tapped into with aftermarket stuff or a clamp meter setup can be used between the inverter and the grid.

I'm confused, no wait... maybe I'm not...

Many thanks yahoo2 for your vote for Fronius. At this stage I�m concluding that there is not a big difference between the two brands for my purposes, judging by the absence of passion on this topic.
