Mercer5m Posted July 10 Share Posted July 10 Hello, I don't have a manual but need to confirm; Max PV Current input - ## A? Maximum PV Array Power - 3000 W? MPPT Range @ Operating Voltage - 60 VDC - 115 VDC? Quote Link to comment Share on other sites More sharing options...

Use Voc not over about 115V which is mostly 2 panels in series and a few strings in parallel. It is not clear what the maximum amp input from PV is as Mecer never specified it. From the manual.

MPPT Range @ Operating Voltage - 60 VDC - 115 VDC? Yes i agree with @Scorp007. I checked back on my installation records and i done an installation 2 years ago using the same inverter (MECER Axpert MKS DS 5000VA / 4000W) and i used 6 x JA 550w panels in 2S3P configuration( 3300w). Imp 13.13A so you will have ~39Amps Mppt input with close to 60A output at perfect solar conditions. Scorp007 1 Quote Link to comment Share on other sites More sharing options...

Above 130 V the output linearly ramps to 0W at 145 V (so 33% power at 140 V for example). So you can exceed Voc of 130 V for unusually cold weather, though it's best not to as the solar charge controller seems to be less efficient at high buck ratios (high PV voltage). The firmware for the 145 V max PV models seems to work OK, but the code is really hard to read. Quote Link to comment Share on other sites More sharing options...
