Off-Grid Solar Kit 28Kwh is a large off-grid solar kit that has a total of 28kWh’s of lithium batteries, giving you 28,000 watt-hours of useable battery capacity. Plus the 6.5kw watts of solar panels will be generating an additional 6.5kw of power per hour while the sun is shining.

If we assume there are roughly 6 good sun hours in most states, the solar panels will produce around 33+kw of power each day (or 990kw/month). Your solar panels in this kit will recharge your battery bank in 3-4 hours of good sunlight.

We also recommend adding a backup generator to your system. All of our Off-Grid Solar Kit have the ability to hook up to a gas generator which can then recharge your lithium battery bank, extending your power and improving your reliability.

Easily expand the kit down the road with more solar panels, more batteries, AND more output as every component in our HBK kits is expandable and stackable. The LV6548 all-in-one inverters can handle anywhere from 7kw-8kw of solar panel input and you can stack these for more output and more solar.

The power wall batteries are also easily expandable and connect in parallel so you can build the ultimate system as you go!

An off-grid solar power system does not tie in with your local power grid/utility company. So there’s no “selling” excess power back to the power company. Off-grid means your system operates 100% independently of the grid.

Any excess power you’re making during the day goes right into your 2 batteries included with the kit so that you can run your home / RV / cabin/shop/business all night long when the sun isn’t shining.
