Are you interested in going off grid with the Tesla Powerwall 2? The Tesla Powerwall, with its huge 13.5kWh of energy storage IS able to be used in Off Grid systems, enabling you to remove your grid connection completely and kick your energy retailer to the kerb.
The Tesla Powerwall is able to be used in off grid systems where the off grid inverter is generating a grid frequency, enabling what would normally allow only on-grid devices to be used in off-grid solutions.
If you’re already off grid or building an off grid property, this is likely exactly what you’ve been looking for! Why? The Tesla Powerwall for Off Grid systems is able to be stacked up to 9 times, meaning you can have up to 126kWh of energy storage, but most off grid properties will not need more than one or two of the Tesla Powerwalls to ensure the property will always have power available, along with an appropriately sized solar system.
Pair that with a Tier 1 rated solar panel installation, using Q-Cells or SunPower solar panels and you have the perfect match of solar production and energy storage with quality equipment.
The general consensus is: If you have a grid connection, keep it and do not go off grid.
You can shave off a decent majority of your electricity bills with an appropriately sized solar system and Tesla Powerwall Home Battery solution. In some cases, this will enable you to effectively go ‘virtually off grid’ without removing your grid connection, meaning you’re only really paying your grid connection service fee charged by your energy retailer and never have to worry about losing power completely by maintaining your connection to the grid should your solar and storage not suffice.
