Lithium batteries have big advantages on safety, cycle life, energy density, fast charging, temperature range and environmental protection.From drop-in-ready products to custom solutions, Zetara Power lithium iron phosphate batteries are one of the most durable and reliable energy sources on the market. And, they're perfect for powering a wide variety of applications such as golf carts, camping, renewable energy, marine, RV, sailboats,Electrical vehicles, commercial equipment, and more. Take the next step in green energy with rechargeable LiFePO4 batteries.
Residential grid-tied solar with backup power
Secure power for your home during grid outages by retrofifitting your grid-tied system with backup power using proven zetara power's solutions.
Self-consumptionExtra PV power for battery charging. When PV power is low or none, load consumption should take power from the battery fifirst, and from the grid as little as possible.
Off-grid power supplyCut your consumption peak and save money by reducing loads. When the grid is offline, the storage system should automatically switch to off-grid powering in less than 1s, for external emergency load powering
The product has a complete and reliable operation and protection strategy to effectively extend the life of the battery pack. It comes with a variety of communication interfaces and can be directly or indirectly connected to third-party energy management systems.
