What is a solar charge controller?

A solar charge controller is a device that regulates the voltage coming from your solar panel to ensure it’s consistent and safe for your devices. This ensures that your devices are not over-charged, and that you’re able to avoid damaging them. There are a variety of different sizes and types of solar charge controller available, so make sure to choose one that will fit your needs and budget.

Additionally, make sure to read the manufacturer’s instructions before using the solar charge controller—they contain important safety information. With a solar charge controller, you can avoid costly energy bills and protect your devices from damage. So, whether you’re just starting out with solar power or you’re looking to upgrade your system, a solar charge controller is a great investment!

What is a 700W solar panel

A 700W solar panel is the most common type of solar power panels used in residential applications. This means that a charge controller that can handle 700 watts of power is a good fit. Next, you’ll need to calculate your wattage requirements and size of grid-tie system (or off-grid) you will be using. Once you have this information, you can find a charge controller on the market that meets your specs.

A typical 700w solar panel setup can produce about 55ah per peak hour. However, this amount will depend on the time of year and where you live. If you have five hours of sunlight per day, then you should expect a 700W system to produce around 300-350ah a day. Depending on the time of day, you might need a battery that is twice as large, or one that can store more power.

A typical 700-watt solar panel will generate at least 30 amps per hour in ideal conditions. The amount you’ll receive will vary depending on several factors. Here’s a breakdown of the factors that affect the amps your system can produce:

You will have to have a 30 amp solar charge controller for the system at least.

If your system is 24V, divide the total solar panel power by the battery system voltage and add 25% safety margins to get the charge controller size.

We recommend you use a 60A MPPT Solar Charge Controller for your 700W Solar Panel if your system is 12V, and a 30A Solar Charge Controller is your system is 24V.
