Hello everyone new to the forum hope someone can help me with this one because it is driving me crazy 
.
I have had a Renogy 1Kw grid tied system with Enphase micro-inverters on my shed for several years now and everything has worked beautifully. I recently wanted to add batteries to my system so I could get some extra power for a couple of hours at night. I purchased the neccessary MC4 splitters a Renogy 30amp PWM charge controller(Model# PWM30-YS), batteries and a grid-tie inverter. I have 4 105 AH batteries setup for 24 VDC and everything seemed to be working fine untill I noticed my Enphase Micro inveters had stopped producing power. After some troubleshooting I found my Batteries were at about 25 VDC but when I checked the voltage at the panels through one of the splitters the voltage was down to 15 VDC. With only one solar panel connected to the batteries through the charge controller the voltage was around 25 VDC but once I connected a second panel to the batteries the volts start to jump from 15-26 vdc and eventually end up at 15 VDC which is to low for my micro-inverters to produce any power. If you need anymore info please let me know. Thanks
