The problem of inverter charger not charging batteries may have several causes. The batteries may have too much load, not enough power, or too high a charge current. Check the battery connections for corrosion and tighten them to ensure proper charging. If you cannot solve this problem, you may have a loose connection. Check the power cords of all batteries to ensure they are properly connected to the charger. If you can’t find the source of the problem, try contacting the manufacturer of the charger.

What is a Inverter Charger

The inverter charger is a device that combines a solar controller and an inverter. By placing it in a home or rv solar system, you can directly use its charge controller function to manage the charging process, and also use the built-in inverter to directly drive household appliances without the need for an external inverter on the battery.

Some inverter chargers may not charge the batteries fully, for example, the float voltage is too high. A battery should be at least 54.4v, and the inverter should stop charging it when it has reached 100% SOC. If the float voltage is too low, it may be because of the manufacturer’s settings for bulk charging, such as 58v. Check the manual for your particular model to find out what the problem is.

Inverter Charger Trouble Shooting: Problem, Cause and Solutions

Provided below is a general list of common inverter charger not working problems, and a few quick fixes that may help solve your dilemma. There are also many links to items within our online store. These link to the most popular products in that category, and may not necessarily fit your inverter controller. Always remember to check your owners manual to ensure that the correct parts are purchased.

PROBLEM	CAUSE	SOLUTION
Inverter Charger not charging	Charge Parameter Setting Wrong	Reset Charge Inverter Charger and setting it as manual guide
	Battery Voltage Setting Wrong	Let Controller Auto Detect or Manually select
	Battery Type Setting Wrong	Select right Battery Type (lithium, lead acid or AGM)
	Charging Protection Mode	Waiting or Reset the Controller
	Wrong Battery Type	Check whether the battery type is supported
	Wring Wrong	Reconnect the Cables
	Physical Damages	Replace a New Inverter Charger
Inverter Charger not working	Inverter no output	Check whether is reverse connected
	inverter socket no energy output	is the socket it broken, contact with the manufacturer for replacement
	110V or 220V Size Wrong	Replace the correct voltage inverter charger
	Appliance Too big	the power of the appliance must in the working range

If your inverter charger is manufactured by ZHCSolar, you may need to update the software. Some of the latest models have software updates that may fix the issue. Check the Spec Sheet and the Operator’s Manual to find out which version you have. Otherwise, contacting the manufacturer is the best option. If you can’t find any solution through this guide, you may have a defective product. A broken unit can cost a lot to repair.

Inverter Charger not Charging Fixing:

In order to use the hybrid inverter charger better, it is necessary to set up the charge and discharge parameters correctly according to the manual in the initial stage. If there is a problem with the charger inverter, you can refer to the error code indicated on the screen, and resetting the controller inverter is also one of the options to fix it.

Other possible causes include a defective battery. Make sure that your Hybrid inverter Charger is configured properly to avoid such a problem. Otherwise, the batteries won’t receive enough juice to carry the charge. The battery is either dead or rapidly running out of power. The voltage drops so far that charging is impossible. In some cases, the inverter may have a GFCI that needs to be reset. Check the battery wires to ensure that they are connected properly. Make sure the positive and negative wires are connected correctly.

Some inverter models are designed to run on specific battery voltages. Using batteries of the wrong voltage will damage the inverter and the connected loads. Ensure the cables are the correct size and are secure. Loose terminal wiring can cause the system to shut down. You should also clean the battery. If you can’t find the problem in your inverter, it’s possible to repair it yourself.

If this doesn’t work, you may have a blown fuse. If this is the case, check the fuse inside the battery disconnect switch. If it doesn’t, the main breaker box will not function. When it is connected to shore power, the AC goes to the inverter, while the other AC goes to your home and AC loads. If the Charger inverter doesn’t detect any AC power source, the micro will stop charging.

If your RV inverter charger still doesn’t work properly, the issue could be in the electrical board or battery cables. Check the voltage of your battery before connecting it to the charger. Then, try reconnecting the AC power. If the problem persists, contact the manufacturer. They should be able to help you find a solution to your problem. If your inverter charger is not charging, you can replace it.
