With a grid-tie system you do not need battery storage. If you produce excess power during the day it can be “sold” to the utility and you receive full credit for the power. During the night when your solar energy system is not producing power you can use that credit against the power you purchase from the utility.

However, if you want power when the grid goes down an energy storage system will be needed.

We offer several options for batttery energy storage including:

SMA with BYD
Canadian Solar EP Cube
Enphase Encharge
Growatt
SolarEdge
EG4 Electronics

Pricing
