Backup and savings with the Chint Power Systems CPS ESSR
From 5 kWh to 20 kWh of storage, the Chint Power Systems CPS ESSR stores daytime solar for the evening and night, and with a backup-capable installation keeps a home running through a power cut. It delivers 2.5 kW of AC power (up to 10 kW in larger configurations), suited to backing up essential circuits.
One full charge covers about 17% of an average US home's daily electricity use of 29.6 kWh.
Its LiFePO4 (lithium iron phosphate) cells are the long-life chemistry of home energy storage: rated for thousands of cycles and more thermally stable than other lithium-ion types.
| Load | Runs for about |
|---|---|
| Essential circuits: fridge, lights, internet, phone charging (about 500 W) | 9 hours |
| An average US home (about 1.23 kW around the clock) | 3.7 hours |
