How To Attach A Solar Panel To A Battery

How difficult is it to add a backup battery to your solar panel system.

How to attach a solar panel to a battery. Battery storage capable solar pv systems require special wiring and some require a special inverter in order to interface with the batteries properly. That doesn t mean you have to wait to go solar however. 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.

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. We will learn how to connect solar panels to battery through an inverter to output ac current. 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. 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.

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. Solar energy is gaining popularity at an alarming rate. These are known as hybrid inverters. 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.

Connect the panels of a solar bank together if there are more than one. If you wire the solar panels to your charge controller first the fuse of the charge controller might blow. Connect the negative wire of the solar panel to the negative terminal of the battery. To charge a battery with a solar panel connect a charge connector to the solar panel.

This will help prevent a fire or battery explosion in the event of a short in the wiring. It is important to wire this component first before you wire the solar panels. If your charge controller has no fuse you can t use it anymore. In the first step you are going to wire the battery to a charge controller.

Then run wires from the battery to the charge connector making sure to match the positive and negative poles. Be it as the main source of energy or as a back up to the popular power outages experienced on main grid power supplies.
