Low amps or current is one of the most common problems you will face if you are running a solar system. You are literally getting low power output. Why? Low amps in Solar Panels can happen if your solar panels fails to convert the sunlight into energy properly. One of the main reasons for inefficient power conversion is PWM Charge Controllers.
Your Solar Charge Controller won’t let current flow from Load to Panel due to its settings thus the total circuit will have zero amps despite having voltage. Your Solar Panel Circuit has a lot of equipment. One of the main pieces of equipment is Solar Charge Controller. Now if it is broken your entire circuit will be busted.
There is a good chance that you may see there is voltage but no amp (which means current). Why? Solar panels having voltage and no amps are mostly caused by an open circuit. In simple terms, it means your circuit is incomplete or flawed. Causes include using wrong voltage, wrong Connection, problems with panels or solar charge controller.
One of the main reasons for inefficient power conversion is PWM Charge Controllers. Easy Solution to this is to use a way more efficient MPPT Charge Controller. Aside from that Environmental issues like Shading, Bad Weather and Wiring Errors also results in Low Amps. The first thing to notice in this case is charge controllers.
Another way Open Circuit happens is using more Load Voltage than panel voltage. As said earlier current always flows from high voltage to low voltage. When the voltage of your load (Load is something you connect to Solar Panel. Take Battery for Example) exceeds your panel’s volt current would not flow from the panel. It’ll be reversed.
Resetting Solar Charge Controller is one of the most common solutions if your Solar Charge Controller is not working properly. Also if resetting doesn’t fix the problems with Charge Controller consider replacing them. We have already discussed earlier how you can measure Volt and Current with a multimeter.

However, the voltage of the circuit remains constant (equivalent to the voltage of each panel). As an effect of this, we get an advantage that if one panel is heavily shaded, the …
Dead short of a single panel (or series string of panels) is fine. They are rated for full time Imp (current maximum power rating)--And Isc is roughly 1.25x Imp. I would not short them for …

I''m running a single string into an EG4 3000 EHV inverter and one eg4 lifepower 4 48v battery. Over several weeks of trying I can barely hit 1000watts and 3-4 amps on the …
In other words, if the voltage of your battery (the load) is higher than that of your solar panel, then your solar charge controller will not allow the current to flow from your …
The system has basically been running OK, with one exception, i.e. the DC current output from the panels into the MPPT charger maxes out at only 5A or less, even in …
What can kill panels immediately--Instead of connecting + of panel to + of battery bank (and - to -) to charge the battery--Connecting the panels backwards (+ panel to - battery, - panel to + …
