What is a pure sine wave inverter?
Pure sine wave inverters are capable of producing smooth, quiet, and reliable electricity to operate appliances and electronics without any interference. Like its name suggests, pure sine wave inverters produce current in a pure sine wave shape. Renogy inverters also provide overload protection for both DC input and AC output to prevent damage to the components and the unit.

Do I need an inverter in my off-grid system?
Inverters serve as the gateway between the photovoltaic system (your solar panels) and the devices and appliances drawing energy from your system. They turn the DC output collected from your solar panels into alternating current (AC), which is the standard used by all commercial appliances. You will need an inverter to convert DC to AC to power most appliances and devices in your home, from laptop to microwaves.

What do I need a pure sine wave inverter to run?
You’ll need a pure sine wave inverter to run appliances with AC motors, such as microwaves and refrigerators, medical equipment, such as CPAP machines with humidifiers, laser printers, newer TV’s, appliances with electronic timers or digital clocks, and most laptops.

What size solar inverters do I need for my system?
Solar inverters come in a range of different sizes. Like panels, inverters are rated in watts. Because your solar inverter converts DC electricity coming from the panels, your solar inverter needs to have the capacity to handle all the power your array produces. As a general rule of thumb, the size of your inverter should be similar to the DC rating of your solar panel system. So if you are installing a 2,000 watt system, you should purchase an inverter of around 2,000 W. To size your system, we recommend using the Renogy solar panel calculator.
