There are different types of storage systems, can be divided into these main categories:
If you already have a plugin solar kit with solar panels and a micro inverter installed, you can add a storage system between your solar panels and the micro inverter. These systems are generally very easy to install, and in some cases (like the Saturn C B2500) even expandable in a modular way.
If you want to add storage to your first plugin solar kit, an all-in-one solution is best. These systems combine batteries, controllers and micro inverters into a single system. You plug the solar panels in on one side, and connect the system straight to your home socket on the other.
Recently a third category of storage systems has launched, that doesn’t need a direct connection to your solar panels or plugin solar kit. These independent storage systems connect to any household plug, and store all surplus power your solar kit produces. They charge and discharge through your home’s electricity network, and can also be charged with grid energy if you want to top up in low-cost times or have no solar installed at all.
