Offer ended in March 2025: price and conditions are no longer valid.
Until March 2025, Heiwit offered a photovoltaic system of 6 kWp with 10 kWh storage at a special price of 12,500 € incl. VAT!
This plant is turnkey, complete with sodium ion batteries and remote monitoring to keep energy production under control at all times. An efficient system with a optimised inverter for our sodium ion batteries, for an integrated system.
The advantages of sodium ion batteries:
- Long life: estimated life of over 6,500 charge and discharge cycles at 90% DoD with 70% residual capacity (NA-48V210Ah, layered-oxide cells).
- Reduced fire risk: sodium-ion cells have a lower thermal risk than lithium batteries, although not zero.
- Charge and discharge up to 5 kW: recommended depth of discharge of 90%.
- Self-consumption: it stores the energy produced by the panels for use in the evening, reducing what you draw from the grid.
In addition, it was possible to take advantage of the tax deduction then available, making the investment even more profitable.
