What does an inverter do?
An inverter is a device that converts the direct current (DC) stored in batteries into the 220 V alternating current (AC) used in homes. In solar energy systems, it enables the energy produced by panels and stored in batteries to be used by appliances such as refrigerators, televisions, lighting, pumps, and power tools. The category includes battery system inverters, smart inverters with built-in MPPT charge control, and solar pump inverters.
Types of inverters
- Pure sine wave inverters: Produce a clean waveform similar to the grid; suitable for motor-driven devices, pumps, and sensitive electronics.
- Modified sine wave inverters: More economical; can be used for simple resistive loads, but may cause problems with some motor-driven and sensitive devices.
- Hybrid inverters with MPPT charge control: Combine panel, battery, and inverter functions in a single device.
- Solar pump inverters: Run AC pumps directly from panels without a battery.
Selection criteria
The inverter's continuous power rating must exceed the total power of all devices running simultaneously. Since motor-driven devices such as refrigerators, pumps, and compressors can draw several times their rated current at startup, the inverter's peak (surge) power capacity must also be taken into account. The inverter's input voltage (12, 24, or 48 V) must match the battery bank voltage. Because higher currents are drawn for the same power at lower voltages, 24 or 48 V systems are preferred for higher power requirements.
Installation and safety
The cables between the inverter and the battery should be kept short and sized for the high current involved; undersized cable causes overheating and power loss. A suitable fuse must be installed on the battery line. The inverter should be mounted in a ventilated location protected from moisture, and the cooling fan vents must not be blocked. Grounding must be carried out in accordance with the manufacturer's instructions.
Frequently asked questions
Pure sine wave or modified sine wave?
A pure sine wave inverter is recommended for pumps, refrigerators, and sensitive electronic devices.
How much battery does an inverter consume?
Consumption depends on the power of the connected devices and the inverter's efficiency. It also consumes a small amount of energy while idling.
Can a 12 V inverter be connected to a 24 V battery?
It should not be; the input voltage must match the battery voltage.
What is the advantage of an inverter with MPPT?
It combines the charge controller and inverter in a single device, simplifying the installation.
Can a water pump run on an inverter?
It can be run with a pure sine wave inverter of sufficient power; the startup current must be taken into account.
What cable size should be used for the inverter?
It is selected based on the current between the battery and inverter and the cable length; follow the manufacturer's recommendations.
