I have 1200 watts of solar on my RV roof and a Smart Solar MPPT 150/70 controller. Right now, I have all the panels in series and the controller sees a volatage of 147V from the PV. This is correct. When I enable the controller to charge the battery, the voltage drops to 98V and current shows 2.2 amps in good sun while the solar shows 218Watts. I have two 6V agm batteries in series. I also have a BMV 712 and those number also make sense, although I'm not 100%.
1. Am supposed to see a number closer to the Wattage of my PV array (1200Watts)?2. When charging in Bulk Stage, the blue LED blinks every 3 seconds although voltage shows 99+ Volts.
3. When the charger switches to Absorption, the amber LED blinks every three seconds.
If something is suspected wrong, what steps can be taken to troubleshoot it? I am pretty technical but don't know where to start as I'm not sure what readings I am supposed to be seeing and if the ones I'm seeing are correct or way off.
