Bosch is selling a near plug and play energy storage system for home use, the BPT-S 5 Hybrid, a refrigerator-sized cabinet that houses a large battery, charge controller and inverter, to simplify integration with a house’s existing solar and grid lines. Installation is estimated at a mere two hours! It’ll charge up when your solar panels are producing excess energy, and discharge that into your house as needed at night. Unfortunately…it’s only available in Germany at this point. 🙁
