How To Charge An Inverter With Generator?

An inverter is among the best instant energy options when there is a sudden power cut-off, but what if in such conditions of long power cuts, your inverter batteries are not charged anymore?

There are plenty of options to charge your inverter batteries. The most common ones are running an automobile motor, solar panels, or a gas generator.

Can A Generator Charge An Inverter?

Out in the market, the inverter generators available mostly have a 12-volt output, which is enough to charge but when it comes down to it, they are not designed to directly charge your batteries.

The main reason is if the generator is operating at a low load it is acceptable to charge the battery but if it is operating at a medium to high load, then it is not possible.

The DC outlet on your generator is limited to a maximum current of about 8 amps. As a result, any battery will take some time to fully charge.

Also, the voltage of the DC output is not regulated; it varies with the RPM of the generator. Furthermore, the generator will not reduce the charge when the battery is nearly full, so you cannot leave it charging for an extended period of time.

How Does An Inverter Work?

Inverters convert direct current (DC) power from a battery to alternating current (AC) power, which can be used to power a wide range of devices, including electric lights, kitchen appliances, microwaves, power tools, televisions, radios, and computers, to name a few. Inverters can be found in a variety of setups.

The inverter may be connected to a battery and your AC equipment can be plugged in whenever you need them.

It is possible to use a single deep-cycle battery or a series of batteries linked in parallel to power the inverter. As the inverter receives power from the battery, the battery will need to be rechargeable. You have two options for recharging: a generator or an AC outlet.

Why Is The Inverter Not Charging Properly?

An inverter is being used in numerous applications and sometimes the load is more than its capacity. As a result, it is obvious that it may fail or break down which can result in service interruptions and significant losses.

An inverter is one of the most overlooked electrical items in a home. We usually overlook its upkeep until there is a problem with its operation. Electricity stored in batteries is transformed from direct current (DC) to alternating current (AC) via inverters.

The most common cause of failure of an inverter is improper installation. Aside from that, other factors that can impede an inverter’s smooth charging include:

Dead Battery:

A dead battery is one of the most common causes of the inverter not charging. The only way to solve this issue is to replace the battery. You can easily buy an inverter battery on your own or with the assistance of a professional.

Burnt Rectifiers:

Rectifiers are basically step-down transformers that can burn out in some cases. In this case, the inverter must be repaired. This could occur as a result of the cooling fan failing to function properly. To avoid problems, ensure that the internal circuitry is of good quality and nature.

Melted Fuses:

One of the causes of the inverter not working properly is a melted fuse. The most common reason for blown fuses is reverse polarity or a short circuit within the appliance.

Also, if the inverter is overheated or used, there is a chance that the fuse will melt or blow off. In such a case, the device must be disconnected and a new one installed by a professional.

Loose Battery Connection:

One of the most common causes of an inverter not charging properly or at all is a loose battery connection. In this case, you must inspect the battery terminals for corrosion before cleaning and properly clamping them.

What’s the distinction between a generator and an inverter?

A mechanical alternator produces ready-to-use alternating current (or AC) power in conventional generators. Inverter generators also use an alternator to generate AC power, but this current is converted to direct current (or DC) before being inverted back into cleaner AC power by a microprocessor.

What causes inverter generators to be so quiet?

Inverters use a smaller engine because of their compact design, which reduces noise levels. Inverters are made of insulated, sound-attenuating materials that absorb generator noise, making them an ideal power source for camping or in residential areas.

Can an inverter be powered by a small generator?

Inverters do not use power generators; instead, they convert DC voltage into AC voltage, which can come from batteries or directly from solar panels. Some inverters can also function as battery chargers; they have an AC output as well as an AC input that can be used as a power generator.


Inverters are critical devices that must always be in good working order to avoid disruption and inconvenience. If you are experiencing problems with its operation or charging, have it checked and resolved as soon as possible.
