Hi guys. This is my first post and I don't doubt that this question has been asked many times before so I apologise for not finding any related threads so far.
I fitted out our camper with leisure batteries and a piddly little 100watt flexible panel some years back (to an EPever MPPT and 2 x 120ah AGM batteries). The panel only provides 40 watts peak now (it's broken somehow) and was too small for the job anyways.
The question is, I think I have enough room for 2 x ECO-Worthy 170watt panels and just enough at the front for a 120watt version of the same. I know that it's pointless to series these to a MPPT but can I put them in parallel? The VOC and panel voltage are quoted as identical so I think I can but i've never put any panel in parallel before so I didn't want to make any mistakes here and to obviously get the full current available from these panels. These are the quote specs from the manufacturer. Thanks in advance..
