ok so my husband set this up with our solar panels after last year's ice storm knocked out our power for 6 days. we were NOT going through that again lol. its been running perfect since april. we run the fridge, some lights, and the TV off it at night no problem. honestly dont even notice the difference from grid power. customer service was really helpful when we had a question about the wiring. 5 stars no question

how many of these can i stack together
A1 SolarStore
Great question! The RGS51205 allows you to stack up to 4 units together, which would give you a pretty impressive 42kWh of total storage capacity. That's more than enough for most residential setups and even some light commercial applications. Just keep in mind you'll need the base and lid unit — those are sold separately but are required for installation.
