Customizable BigBattery Home Inverter and Battery Kit for Grid-Tied or Off-Grid Renewable Energy Systems

The batteries are the part of the system that store energy for the inverter to use as needed to power appliances and loads. Since the APEX inverters are all based off 48V batteries, all of the batteries listed here are also 48V batteries.

Choose the ETHOS for 10.24kWh of stackable storage, which can be expanded with additional modules. This battery utilizes quick connectors on their positive and negative terminals.

Choose the NEXUS for 15kWh of compact and energy-dense storage. The stud terminals allow for a broad selection of cabling, which makes finding custom power cables considerably easier. The cables provided with the battery are 4 AWG with 5/16" ring terminal lugs on one end and 3/8" ring terminal lugs on the other.

Choose the HUSKY 2 INV batteries for configurations that require a smaller footprint. This battery also uses stud terminals for custom cable lengths, and it works great for less conventional setups.

Solar panels are a great way to add in renewable energy to your system. A solar charge controller is conveniently built into the APEX inverters to convert the energy made by the solar panels into usable power for the inverter to pass onto loads or to charge connected batteries.

If you have solar panels, you'll need a way to mount them. IntegraRack's mounting options are fast and easy to install.

The BallastRack series works great for ground mounts, though you'll need a way to secure the frames. IntegraRack makes a few options that we'll explore in the next section.

The BallastBase and MultiBallast series is great for flat roofs or flat ground mounts. These racks utilize concrete blocks to weigh down the panels and prevent lift even in wind storms. Alternatively, you could use the SIKAFLEX epoxy in the next section to glue down the racks to reduce weight on the roof.
