Are you exceeding max input volts?
Your HQST panels have some performance numbers on the back. If you wired 4 panels in Series, then the voltage on the wire ends (before connecting into the MPPT Solar Controller should be very near 4 times the V(oc) of a single panel., even under moderately strong sun (without shade). There are many possible problems here.... including (most disastrous) the possibility of 4 times V(oc) exceeding the maximum PV Voltage of your MMPT Solar Controller. Example: If you had 4 panels with V(oc) of 22.0 Volts each, wired in Series to make 88 Volts V(oc), and you plugged that into a "60 Volts maximium" MPPT controller, then you will have fried the MPPT controller. A 36 Volt reading is possible near sundown, very late in the day.Found a multi meter I’m confused I’m getting 34 volts on a evening sky. What’s going on?
Yes connected the battery first 8 ga marine tined copper 1 foot run from Epever 40 amp mppt. 12/24v auto working max 150v regulator tracer Bn series neg. ground control/. HQST 100 solar panel mod. HSP 100 DL. No inverter 12 v distrablution system has no fuses so. Not drawingMore details would help.
Did you connect the battery first, then the panels?
What model charge controller?
What makes you think it is not working?
From panels to mppt terminals 32.7 v, battery at mppt 36.5 v
Glad you got it working. As mentioned a few times, even if the sun was out, a full or nearly full battery will show little current going into it, The only way to fully check your panel output is to load the battery more than the panel ratings.Fixed that hooked it all up and now am charging the battery all be it slow as it is raining. sometimes it’s the tiniest things that get us all ape.
