I would like your input on what could be the issue with my solar system in my van.
My system/van was recently completed, and I am finding the electrical is behaving like it cannot get enough power. And when the sun sets, there is NO solar power available, even though the batteries are fully charged. ?
My system will run puck lights and fans and water pump during the day, but if they run too long it starts to fail… lights dim and go out, fans stop. I have a 12 volt Whynter frig that also will not stay charged.
My inverter will go into “fault” mode and not work.
Here are my components:
- Victron Energy SmartSolar MPPT 100V 30 amp 12/24-Volt Solar Charge Controller (Bluetooth) (**note one of the pictures shows a renogy Rover MPPT, I switched it to the Victron MPPT)
- Victron Energy BMV-700 Battery Monitor
- Victron Energy Lynx Distributor
- 2 x Renogy 200-Watt 12 Volt Monocrystalline Solar Panels
- 3 x Renogy 12V 100AH Smart Lithium Iron Phosphate Batteries
- Giandal 3000W Pure Sine Wave Inverter 12V DC to 120V AC
My solar panels are set up in series since there are only two.
The readings I get on my Victron Smart Solar app are:
Solar
Voltage: 45.96
Current 0: amps
Battery
Voltage: 13.5
Current: 0 amps
State: Float
I have tested continuity of the lines on a multi-meter, and they all have constant current coming through. So power IS able to get through.
I have checked the various lines with the multi-meter to make sure they are getting above 12-13 volts, and they are.
Batteries read at 13.49v with multi-meter. (also, dumb question, but does that 13.49v read indicate they are completely charged? The victron Battery monitor DOES say they are, but I always wonder if its right?)
We checked the connections, all are properly tight.
I just don't know where the issue is. Any thoughts/help would be greatly appreciated.
Thank you in advance.

Heads up all... I think I have my answer.
I just checked the actual terminal block fuse, and it IS blown. There is no continuity from one side of fuse the the other. So I think this is the problem.
Thank you to everyone who jumped in to help me. Thank you!
