from 45 kWh to 90 kWh
You need more storage capacity than usual and want to be on the safe side. Because you have installed a lot of photovoltaics on your commercial roof, apartment building or agricultural land. You need more power for your various consumers, some of which are sensitive. Emergency power supply or islanding capability is very important to you. What if there were an uninterruptible power supply that is not only operational when everything fails, but also optimises your own consumption all the time and thus generally reduces your electricity costs? You would have cost-effective security!
innovenergy® offers you a safe profitable salt battery storage system including UPS:
- 24 or 30 kVA inverter capacity (400 V)
- Salt battery storage capacity from 45 to 90 kWh – can be expanded at any time through simple plug-in units in the rack
- Safe control and take-over of power supply in less than 20 milliseconds in case of mains failure
- Existing online UPS systems can be integrated
- High operational safety – no fire hazard
The salipro® is an AC-coupled salt battery storage system that automatically switches to off-grid operation in less than 20 milliseconds and continues to operate autonomously. It guarantees the safe continued functioning of your commercial enterprise. The AC-coupled salt battery storage system works with all PV inverters. Suitable solar charge controllers can be installed as an option. After a mains failure, energy continues to be stored in the battery or the stand-alone grid. Depending on the project, a choice can be made between a battery inverter output of 24 or 30 kVA.
The following salipro® are available:
|Number of batteries||Storage capacity||Inverter capacity|
|up to 5 batteries||up to 45 kWh||3 x 8 kVA = 24 kVA|
|up to 10 batteries||up to 90 kWh||3 x 10 kVA = 30 kVA|
This list is only indicative and may vary depending on project requirements. This will be worked out in the preceding engineering. Our sales partners will be happy to advise you.

In the event of a grid failure, the photovoltaic power is no longer available. However, the battery system can continue to be used until it is completely discharged. UPS means uninterruptible power supply. This means that in the event of a mains failure, the system automatically switches over in less than 20 milliseconds and continues to function autonomously.
With an off-grid battery storage system, the photovoltaic power continues to be available in whole or in part. The battery can continue to be charged and surpluses are available for consumption in the off-grid system. This extends the period of self-sufficiency from the electricity grid. Here, too, the system switches automatically in less than 20 milliseconds.
|Mains independence||asymmetrical 3-phase operation|
|Recharging by PV in off-grid operation||DC -> DC: Victron MPPT|
|Separate emergency circuit||≤ 24 kVA or ≤ 30 kVA freely definable|
|Switchover to off-grid mode||automatic (in under 20 milliseconds)|
- Potential-free contact for switching consumers on and off (charging station, heat pump, etc.)
- Time control for recharging the battery from the mains (calibration 100 % SOC)
- Lifetime-optimised operation of the battery (discharge protection during bad weather periods, consideration of the weather, power limits)
There are no early recycling or disposal fees. However, the transport of the battery to be discarded back to the manufacturer in Stabio/CH must be borne by the customer. There, the complete battery is returned to its raw material cycle.
KFW subsidy in Germany is available with a 10-year current value guarantee.
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.
If the storage demand increases, additional batteries can be added at any time (even years later) without any problems. The storage capacity then increases by 9 kWh per added battery.
Further information can be found in the detailed circuit diagram and in the connection example without emergency power or in the connection example with emergency power.
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.
