How To Add Battery To Solar Panel

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.

How to add battery to solar panel.

Figures from the climate council show that adding a 4kwh battery to a 5kw residential solar system can increase the amount of self generated solar electricity a household consumes. Connect the panels of a solar bank together if there are more than one. Once you add a solar battery to the mix the economics become more complex. Unfortunately this process isn t as easy as simply hooking up a new battery bank.

Grid tie inverters are designed to convert dc direct current from solar panels but they are not designed to integrate with a battery bank. With a dc coupled system your inverter will be replaced by one that works with a battery and a solar system. For example a solar panel must be capable of producing 0 5 amp hours of energy per day to maintain the charge on a 50 amp battery. Dc power produced by your solar panels is used to charge the battery.

With a standard solar energy system the economics are fairly easy to understand. If you have high electricity bills installing solar panels to produce your own power is an investment that will pay off in just a few years. Battery storage capable solar pv systems require special wiring and some require a special inverter in order to interface with the batteries properly. 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.

If you have a storage ready solar system you already have an inverter that can easily integrate a battery into your solar panel system. A solar battery lets you store the surplus electricity your panels create so you can use it later in the day and can in fact almost double how much solar you use. It s also not cheap. From there the power is passed through the hybrid inverter which converts the power into ac electricity.

You ll typically need to add new components to make your inverter work with your batteries. 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.
