As from 2022-2023

In 2022 I installed a battery (48 V, 60 kWh) and an 3 phase 24 kVA energy storage system (ESS) from Victron.

A 4 kWp unit from 2002 on the east roof was disconnected from the grid in August 2022 and reconnected to the battery (DC-DC). In June 2023 I replaced the 4 kWp from 2002 on the south roof with a new 11 kWp unit (connected to the battery). I also added a 4.9 kWp unit on the garage (battery) and disconnected a 2.7 kWp unit from the grid and reconnected it to the battery.

So after 2023 four units (4 kWp, 2.7 kWp, 11 kWp and 4.9 kWp) are connected to the battery and one unit (10 kWp from 2017 is connected to the output of the ESS system (DC-AC, 3 phase).

Unit 2002: 4 kWp, angle of inclination 30° azimuth -75° (75° east) to battery
Unit 2008: 2.7 kWp angle of inclination 19° azimuth +15° (15° west) to battery
Unit 2017: 2x5 kWp angle of inclination 10° azimuth +90/-90° (east/west) to AC output ESS 3p
Unit 2023: 11 kWp, angle of inclination 45°, azimuth +15° (15° west) to battery
Unit 2023: 4.9 kWp, angle of inclination 45°, azimuth +15° (15° west) to battery
