Benefits for the installer and investor
ROI for a 3-phase house: 8–15 kWp installation with 10–20 kWp storage kWh allows you to increase self-consumption from ~30% (without batteries) to 70–85% (with storage). The return on investment in net-billing is 7–10 years, and the battery life (10+ year warranty) significantly exceeds this period.
Annual savings: for a family of 4 consuming 5-7 thousand kWh Annual savings of PLN 4–6,5 compared to purchasing electricity from the grid. Thanks to the EPS function, you get the bonus of emergency power.
After-sales support: assistance in pairing the inverter with the battery, configuration of operating modes (self-use, backup, peak-shaving), activation of Solarman Smart/Solarman Cloud, support with reporting to the DSO and warranty service throughout Poland.
For the installer: attractive margin, fast delivery, service pre-authorization, marketing materials for end customers, online training on hybrid system configuration.
Installation and commissioning
The 3-phase hybrid system is installed by a qualified electrician with SEP E certification up to 1 kV and trained in battery installations. The process includes submitting a micro-installation application (up to 50 kWp) or requesting conditions (above 50 kWp), installing the inverter and battery (typically 1 day), setting up self-use/backup modes, and launching Solarman Cloud monitoring. Time from purchase to a fully operational system: 1–4 weeks (micro-installation) or 6–10 weeks (above 50 kWp).
