#Off grid battery bank install#
In these cases, it is more cost effective to install a single stand alone off-grid system than pay the costs of having the local electricity company extend their power lines and cables directly to the home.Īll stand-alone and battery backup alternative energy systems whether wind, solar or hydro powered all require some form of battery storage so its important that connecting batteries together is done correctly.Īn electrical generator charges the batteries, usually during daylight hours for solar and the batteries supply the power when it is needed, often at night and during cloudy weather, so connecting batteries together to store this free solar energy is and important part of any off-grid renewable system. Off-grid systems are ideal for remote rural areas and applications where the connection to a utility grid is either impractical or unavailable. Off-grid or stand alone systems use batteries to store their electrical energy. Battery based grid-connected systems require a different type of inverter as well as a battery charge controller to monitor the flow of electricity into and out of the battery bank.
Grid-connected systems are so named because they connect directly to the electrical utility grid and if the electrical generating device, solar panels, wind turbines, hydro generator, etc, is producing more electricity than is needed, the excess is fed onto the grid.īut grid-connected systems with battery backup (Hybrid Systems) are also possible. Most alternative energy generating systems fall into two main categories, a “grid-connected system”, and an “off-grid system”. Connecting Batteries Together Connecting Batteries Together For More Battery Storageįor either off-grid or grid-connected reneable energy systems that use batteries for their energy storage, connecting batteries together to produce larger battery arrays of the desired operating voltage or 24 hour current demand is an important part of any solar power energy storage system.
