For someone starting with one battery who expects to fill a rack or add racks later.
The EG4 Battery Starter Kit is perfect for a system geared towards expansion. First, choose between the LL-S or LifePower4 lithium batteries and choose your quantity. Next, choose between a 3-slot rack or a 6-slot rack. Both are easily expandable, have pre-installed busbars for paralleling, and have wheel attachments for arranging the best use of space for your system. For the 3-slot rack, we’ve pre-selected 2/0 AWG cable to connect the rack to the inverter. For the 6-slot rack, we’ve pre-selected 4/0 AWG cable to connect the rack to the inverter. Those wire sizes are appropriate for a full cabinet, so there’s no need to change cable if you start with 1 battery or fill the whole rack. Lastly, there is an optional communication cable. This would make the run from your leader battery to the inverter or communication system, or to go between racks for larger expansion.
Warranty terms mentioned in this description are the manufacturer’s. Our own coverage is the 30-day limited warranty.
We confirm compatibility, installation requirements, and delivery details with you during order review, before any payment. Home electrical work may require a qualified installer.
