Also going to reconfigure batteries for 36v.
I'm installing 6-370 watt panels in parallel to my Flexmax60 charge controller. Is that too much wattage for that controller?
Well, like so many things, it really all depends on the EXACT specs of the PVs. Assume that you have a 24 V system, still.
BUT, the OB FM60 and FM80 have a Maximum total PV Isc spec -- 80% of the output current rating. For the FM60, this is 48 A total for the sum of the Isc rating of each string, or of each PV, it the PVs are singles, all in parallel.
What is the manufacturer and model number of the 370 Watt PVs that you would be using?
Hello Vic: Thanks for replying. Yes, 24 volt system. Here are the panel specs:
Re your original question, the total maximum Isc for six of those PV all in parallel, is 59 Amps. The Limit for the OB FM60 is 48 Amps, so, the proposed configuration results in excessive total PV Isc.
Strings of two of the PVs should be OK, as that halves the total Isc (29.5 A).
OR, an FM80 (64 A total max Isc rating) should be OK with all six PVs in parallel.
The way I see it, Vic
Well, five of the 370 W PVs on an FM60 is certainly less-risky than are six.
It would probably be OK, in most situations, but, still a bit over-spec on the max PV power. Would worry less about being about 2% over the total max Isc.
Your decision. Good Luck, picking nits, over for now. Vic
