Connect your battery to the inverter, charge controller, and charging source. Next, connect your home battery backup system to your home's existing wiring using a transfer switch (or power input, if available). Once everything is hooked up, your home electrical system should draw from the backup battery the next time a power outage occurs.
Building a home battery backup system requires more than just a battery and some wires. You need to connect the battery to your electrical panel and ensure compatibility between all system components. Still, the DIY process doesn't have to be too complicated.
The Energy Storage System uses a MultiPlus or Quattro bidirectional inverter/charger as its main component. Note that ESS can only be installed on VE.Bus model Multis and Quattros which feature the 2nd generation microprocessor (26 or 27). All new VE.Bus Inverter/Chargers currently shipping have 2nd generation chips.
Policy 2: Keep batteries charged: Use ESS, select the “Keep batteries charged” mode. And enable “Feed-in excess solar charger power” Policy 4: Prevent feeding energy to the grid: There are two options here; first - use ESS, but do not enable Solar charger excess feed-in and it will always be connected to the grid.
