With a home battery store energy during the day and use that energy during peak times to save money

Produce Low & Sell High

 Ordinarily, the energy landscape is skewed, favoring utility companies. In California, electricity rates plummet during early daylight hours due to plentiful solar energy, but they skyrocket in the evening and nighttime, more than doubling in cost. It's a cycle of buying high and selling low. However, there's a way to outsmart these utilities—by harnessing the power of rooftop solar paired with smart battery solutions. With this combo, you can store the solar energy you generate during the day in your own system. Then, when rates peak later in the day, you can rely on your stored energy, buying any energy needed at a low cost and selling energy back to the grid at their high price. It's a game-changer in the energy world.
