July 16, 20215 yr Pardon chaps - answer to this is most probably already in the forums... i have been searching but i will ask anyways. I'm looking to add additional pv panels to my current setup (2 x Axperts in parallel). I'm only using the one inverter's MPPT at the moment (12x330w seraphims). Popped in at rubicon ct today - they only had 490W panels. No problem 2s4p? it is then. Lemme have eight. But the dude behind the counter was adamant I should rather buy more similarly specced panels to the ones I currently have... (who stocks seraphims anyway?). "But its going to be connected to the 2nd inverter on the unused mppt" I said. "Yeah but the inverters are connected in parallel", he reasoned. Me thinks the bloke was just confused but now am doubting myself. Eight of the 490w should be fine right? Also, this new array will be installed flattish on a carport facing NNW. current setup is facing NNE. My two axperts are of the standard 60 VDC~115 VDC mppt variety, connected to 14.4kw storage. Panels in question are the cs 490w hiku5 mono.

"But its going to be connected to the 2nd inverter on the unused mppt" I said. "Yeah but the inverters are connected in parallel", he reasoned. He is wrong. The two solar charge controllers are separate, so they can have totally separate voltages and so on. 20 hours ago, MockTurtle said: Eight of the 490w should be fine right? Without looking up the specs, it sounds fine. 20 hours ago, MockTurtle said: connected to 14.4kw storage. I assume you mean 14.4 kWh of storage.
