Have you got a grid tied inverter or DC device that takes solar panels but cant benefit in terms of the high demand tariffs due to weak sun in those times?
Step into the world of Battery-PV DC coupling.
This revolutionary system allows customers to drastically reduce their power bill with their current grid tied setup by storing excess solar energy thought out the day and then only using it during the peak times, allowing for a much better ROI.
How this system works: when your grid tied inverters are not under load the battery will absorb all the excess power from the PV and when the sun goes down the battery will turn on its discharge contactor to allow discharging directly into the grid tied invertes PV port acting as your own little sun!
