Hi,

I have read elsewhere on the forum that cerain Infinisolar inverters have internal fuses for the PV and battery connections.

Where are these fuses located, and can they be easily replaced by a normal person (meaning not an Inverter specialist)?

Hi Frodo, Welcome to the forum. I am only aware of a battery fuse, If you look at the picture supplied, and you remove the right hand side cover as well. Arrow one will point in the general direction of the fuse. the red wire from the battery connection terminal connects directly to the PC board mounted fuse. 

The other 2 arrows point to the Pv input wires. I haven't seen  a fuse on that circuit. 

 

 

In one I examined recently, there were 4 ordinary sized (3AB, same size as 3AG but ceramic) in parallel near the battery terminals. This one had a chunk blown off one of the battery terminals, and a note about accidental reversal of battery connections, and yet the fuses hadn't blown. In my experience, fuses in inverters are rarely the problem, but maybe that's because I only get the more difficult cases.

I can't find my photos of that machine at present, sorry.

Thanks.

I would have expected to see some polyfuses on that board, but can't clearly see in the photo if there are indeed any
