Technically, all you need to charge a 12v battery is a solar panel with a 12v rating. This can be any solar panel, although the bigger it''s, the quicker your battery will charge. Anything under 5–10 watts is not enough, as these will only “trickle charge” your battery very slowly. In general, 12v panels are only available up to a rating
Well, an open circuit aka faulty solar panel wiring may be one reason. Another reason is the well-known solar charge controller errors. Basically, your Solar Charge Controller goes haywire and stops current flow. Finally, Internal Problems within the Panel will definitely cause zero amp issues. Maybe the problem was with your panel after all.
Step 2: Connect Your Solar Panels to the Charge Controller . Attach the negative solar panel adapter cable to the negative solar panel cable. Do the same thing for the positive panel cable. Plug the positive solar input cable into the positive solar PV terminal on the controller and tighten the terminal shut.

If you purchase a 12v solar panel you should pair it with a 12v battery (a 12 volt lithium battery will work best with the 12 volt solar panels), a 12v inverter, and at least a 12v charge controller. A 24v solar panel should be used with a 24v battery bank, 24v inverter, and at least a 24v charge controller.
I have a MPPT 100/30 Smart Solar charge controller. I tested the panel and connected it and it worked fine. I then disconnected it so I could mount it on the vehicle roof.
Boost Charging Volt (V):13.8V, an OK value for a low stress charge, set to 13.9 or 14.0 for a slightly faster charge time. Float Charging Volt (V):13.8V, if there is a load on the battery whilst solar is active set to 13.5 or 13.6. If the battery is standby use set to 13.4 or 13.3.
There are several reasons why your solar panel might not charge the battery. One reason is lack of exposure to direct sunlight. So, if your solar panel is placed under a shade or if trees are blocking the sunlight from reaching the panel, then it will not charge.
To check if a solar charge controller is functioning, measure the multimeter's voltage. If the controller shows 0.0amps while charging, there might be an issue with the breakers, input voltage, or wiring.
You have a fully charged battery. 13.8 is a conservative value and will charge your battery, and with the 120 min boost duration, the constant voltage period, will get to full. Boost Charging Volt (V):13.8V, an OK value for a low stress charge, set to 13.9 or 14.0 for a slightly faster charge time.
Check Connections: Inspect all electrical connections between solar components, as loose or corroded connections can disrupt charging performance. Maintenance Matters: Conduct regular inspections and cleanings of your solar setup to maximize battery charging efficiency and prolong lifespan.
To soft reset a solar charge controller, press the power and reset buttons together and hold for a few seconds until the screen reboots. For a hard reset, disconnect the wires from the battery and the solar panels, then wait for a few minutes before reconnecting.
