Is the bundle price all-in?
Yes. €23,500 excl. VAT covers the inverter, battery, Themis EMS (first year), professional installation and grid certification. The only optional add-ons are GAIA panels, the ETAP Pro charger, and Themis from year 2 onward.
How long does installation take?
Most installations are completed in one to two working days. Lead time from quote signature to commissioning is approximately six weeks.
What does the 12-year warranty cover?
Battery cells, BMS, inverter, Themis EMS hardware, and labour for any in-warranty intervention. One contract, one phone number.
Can I extend the battery later?
Yes. The Energywall HV is modular in 3.56 kWh increments. You can start at 7.1 kWh and grow to 53.4 kWh — same inverter, same software.
