Ah.. So a PWM controller are more efficient compared to MPPT on 60 cells 24v systems?

So when i look at this manual it says "-" instead of 1 or 2 max for 60 cell Voc<38v (24v) under Tracer2206AN. Does that mean; dont even try connecting a 60 cell 24v + panel? Best regards,

one PV rated 38.9 Voc on a Epever Tracer 2206AN? Best regards,

Thanks! I agree, one or two of these meters are probably faulty. Wish i knew what to replace for more accurate readings. For one moment i was thinking maybe the inverter just pulls 330W to do its thing.

Yes sir.

Hi guys, To explain this picture.. I have 3 x 295w panels half shaded when i took the picture, connected in parallel to a grid tie inverter. The AC output of the grid tie inverter claim to be over 330W ( 2.855A X ~120V ), but the meter from panels only register 244.1W in.. Do i have the worlds...

I put together a small powerwall using 18650 batteries. 30A should probably be fine, the panels dont have optimum tilt. Thanks!

Thanks for the input guys.. How about this Tracer3215BN from Ebay ?

Hi guys, I got 3 x 295W panels ( 38.9Voc ) & 1 x 150AH 24V lithium ( edit, 3.7v 18650 powerwall ) ion battery i want to charge. What budget MPPT charger would you guys recommend? Connect the panels in series/parallel? Best regards,
