In order to use batteries as part of your solar installation, you need the following components: solar panels, a charge controller, and an inverter. The higher your battery’s capacity, the more solar energy it can store. Solar batteries store the energy that is collected from your solar panels. Regularly going beyond that point will shorten the life of the battery.

Deep cycle batteries can, in theory, be discharged up to 80%, but most manufacturers recommend not discharging below 45%. In contrast to car batteries which only provide short bursts of energy, deep cycle batteries are designed to provide sustained periods over a longer period of time. Deep cycle batteries are what you’ll need for your solar installation, since contrary to a car, you’ll need power for a long period of time and not just in a short burst. Should I use a marine battery for my system?ĭeep cycle batteries look similar to car batteries, but they are actually very different.What's the difference between starting, dual purpose and deep cycle batteries?.Let’s discuss so you know what to look for when deciding on a battery solution. Not all are suitable for a solar installation.

What’s potentially confusing about this shopping process is that marine batteries can be a variety of different battery types, from starter to deep cycle. Especially if you’re looking to add solar to your boat, a marine battery may seem like the best option. As you shop for batteries for your solar installation, there’s a good chance you may come across marine batteries and wonder if they are a viable option for your system.
