How To Attach A Solar Panel To A Battery

The level of difficulty associated with adding a battery depends on whether your solar panel system was designed with the intention of adding energy storage later on.

How to attach a solar panel to a battery.

To charge a battery with a solar panel connect a charge connector to the solar panel. Be it as the main source of energy or as a back up to the popular power outages experienced on main grid power supplies. Just ask your solar installer to design a storage ready system with an inverter that works with solar batteries so you can turn your solar panel system into a solar plus storage system later on. Battery storage capable solar pv systems require special wiring and some require a special inverter in order to interface with the batteries properly.

This will help prevent a fire or battery explosion in the event of a short in the wiring. In the first step you are going to wire the battery to a charge controller. They are usually wired in parallel to preserve the voltage of each panel but you can also wire sets of them together in series to increase the voltage to conform to the voltage of the battery bank if need be. Connect the negative wire of the solar panel to the negative terminal of the battery.

It is important to wire this component first before you wire the solar panels. Inverters that can work with batteries have only been on the market for the last few years so chances are very high that many people considering adding batteries to their solar power system. These are known as hybrid inverters. How difficult is it to add a backup battery to your solar panel system.

With a dc coupled system your inverter will be replaced by one that works with a battery and a solar system. If you have a storage ready solar system you already have an inverter that can easily integrate a. We will learn how to connect solar panels to battery through an inverter to output ac current. Divide the wattage of the solar panel by the voltage of the battery to get the number of amps your charge connector needs to handle.

If your charge controller has no fuse you can t use it anymore. That doesn t mean you have to wait to go solar however. Connect the positive wire from the solar panel to a battery cable with a fusible link between the battery and the solar panel. Connect the panels of a solar bank together if there are more than one.

Then run wires from the battery to the charge connector making sure to match the positive and negative poles. Solar energy is as well used to heat.
