Large salt battery storage system for commerce and industry
from 44 kWh to 2 MWh
You want to constantly expand and maximise your photovoltaics. You need maximum power for your consumers with different outputs. You want to optimise your own consumption to the maximum. Emergency power and off-grid capability are a matter of course for you. And you want to install a system that can be expanded step by step in the future and that grows with your requirements. What if your high claim were to be exceeded? Then you have discovered our salimax®!
Available as early as January 2023. Plan your self-sufficient future with us now.
innovenergy® offers you an economically viable salt-based storage battery system:
- DC-coupled storage battery including 10 kW bidirectional DC/DC converter (on board).
- Maintenance-free salt batteries with 22 kWh or 41 kWh storage capacity
- Storage capacity scalable up to 2 MWh
- 22 kWh salt battery freely combineable with 41 kWh salt battery
- Intelligent control for optimising own demand and peak shaving
The salimax® is a DC-coupled salt battery storage system for large photovoltaic systems and corresponding storage needs. The salimax® can also be installed as an emergency power-capable, off-grid-capable system. This salt battery storage system is equipped with a PV inverter from Trumpf-Hüttinger or, for very large systems, with an Indrivetec (up to 3 MW). The salimax® can be equipped with two battery sizes, which can be scaled and also mixed as desired. Battery storage systems from 44 kWh to 2 MWh can be realised with the salimax®.

Extensions
Up to 64 salt batteries (à 22 kWh) or up to 48 salt batteries (à 41 kWh) can be connected in parallel in 16 racks each. Both types of salt batteries can also be combined. An extension is possible at any time, even years later.
Recycling
100 % of the discarded salt batteries are returned to the raw material cycle. In Switzerland, this recycling is ensured by INOBAT. Different recycling regulations apply in each country and advance disposal fees are charged accordingly. Please ask your sales partners in the respective country.
Subsidies
KFW subsidy in Germany is available with a 10-year current value guarantee.
Warranty
Provided that the installation and operating conditions are complied with, the salt battery is covered directly by the manufacturer with a time-value guarantee of 10 years. The battery inverters are covered by a 5-year warranty. Everything else is covered by a standard 2-year warranty. The warranty is an device warranty. Travel costs and working hours will be charged separately in the event of replacement or faults, unless you have subscribed to a service contract for the relevant year.

Advantages of the salt battery
The salt batteries of the innovenergy® storage solutions are made of harmless materials: 32 % common salt, 22 % nickel, 22 % iron, 20 % ceramic.
The recycling of the salt battery has been standardised for 15 years. The metals are melted down and returned to the metal industry. The battery is manufactured 100% in Switzerland according to Swiss environmental and labour standards.
The salt battery is absolutely safe - the rooms do not need any fire protection or fire warning devices as the battery is neither flammable nor can it explode. It can also be operated in very cold and very warm rooms (-20° to +60° C) without ventilation or air conditioning. The outside temperature does not affect the storage capacity or the service life.
The battery survives a total discharge without damage. The salt battery has a service life of at least 15 years (10-year guarantee) and is maintenance-free.
The salt battery is extremely robust and is used by the thousands in the telecommunications industry. In industry, it is considered a cheap and safe electricity storage technology in the long term. With innovenergy®, this technology is now also available for domestic use and for businesses.
