Installed this hybrid 30kVA Three Phase system in Belfast for a popular guest house. The challenge in the area is poor grid voltage supply, regularly in the 180V region, and frequent grid outages. This damages equipment and makes for a very high maintenance bill. We are running a Node Red algorithm to disconnect from the grid and run in off-grid mode as much as possible, supplying a stable 230V to the guest house 90% of the time. That on top of the savings from solar production makes for a very wuick ROI. Specs ๐:
- 3 x 10kVA Victron Energy Inverters, configured as a three phase 30kVa system
- 1 x Victron Energy 450/200 MPPT Solar Chargers
- 10 x Freedom Won 5kWh eTowers = 50kWh battery storage
