There are way cheaper options than the Anker Solix 3800. Here are some options, in no particular order:
- $3,300: 10 kWh with 2x EG4 WallMount Indoor 100Ah.
- $3,110: 14 kWh with 1x WallMount Indoor 280Ah.
- $2,690: 10 kWh with 1x Deye RW F10.2 B
- Will Prowse's YouTube channel has reviewed several battery builds that are >10 kWh and near $2,000, but they're DIY assembly.
And still much more than the cost of the solar panels, which was GP's point.
Batteryhookup has batteries for $40/kWh :) just put together a off grid setup for a friend and 8kwh cost $400 in parts!
