Hi all! I need help figuring out what's going on with my solar setup.
First my setup:
12v AGM 100ah battery
Two Suaoki Flex Panels 100Watt each. Wired in Series. Placed right on the top of the roof of my camper with vhb tape.
i have about 30 feet of wiring to the controller. 10 gauge wires.
Controller is Victron Energy 75/15 Mppt.
Issue I am having is that I am getting intermittent charging from the panels. I can't tell if the issue is with the controller or the panels.
I have tested the panels and they seem to produce correct voltage and current.
When wired together in clear sun they both output roughly 40volts. As soon as I plug them into the controller and backprobe the controller voltage drops to about the voltage of the battery.
Interestingly when the battery is fully charged via shore power I get really good voltage to the battery at the controller and via the Bluetooth connected app. This lasts only a few days and then I start getting absolutely nothing.
Right now I am in full sun and the controller is telling me the STATE is "off".
Sadly both Victron and Suaoki has she worst support. Neither have phone support, Suaoki cacan even write in English well enough for me to understand what they are saying and Victron is telling me to go to the dealer I bought the controller from and that company is out of business.
Hope you guys can help me.
I have two thoughts on this.
1. It could be the algorithm built into the controller called BatteryLife which I do not understand how it works.
2. Panels are overheating. They seem to work at least a little when sun is lower in the sky and tempreture is lower. I checked the tepreture of the panels and they are at 140 Fahrenheit right now.
Thank you in advanced for the help.
