Salt battery storage systems for the home
with 9 kWh or 18 kWh
When do you need electricity the most? Sure, in the morning when you get up and then again in the evening when everyone is back in the house. But your photovoltaic system only produces during the day - when you need less electricity. So you feed diligently into the grid. And when you need electricity, you have to buy it again. But what if you could now store your electricity all to yourself, available at any time? You and your house would be independent!
innovenergy® offers you ecologically harmless salt-based home storage for your PV system:
- 9 kVA (3 x 3 kVA) Inverter power (400 V)
- 9 kWh storage capacity (salidomo® 9) – can be expanded to 18 kWh at any time with a simple plug-in unit (salidomo® 18)
- Maximising your own consumption through intelligent control
- Monitoring the power situation and and energy analysis via smartphone app or internet browser
- plug & store – turnkey solution with easy installation

The battery storage capacity for the two salidomo® is as follows:
- salidomo® 9 = 9.4 kWh
- salidomo® 18 = 18.8 kWh
Up to 80 % usable in normal operation, up to 100 % in emergency power operation.

Definition of emergency power
Emergency power
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.
Off-grid operation
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.
Emergency power supply
The salidomo® is optionally available as an off-grid capable salt battery storage system. In this case, the system automatically switches to island operation in less than 20 milliseconds in the event of a mains failure and continues to function autonomously. In order for the battery to continue to use solar power without a grid, a DC/DC solar charge controller from Victron would have to be used.
| Mains independence | asymmetrical 3-phase operation |
| Recharging by PV in off-grid operation | DC -> DC: Victron MPPT |
| Separate emergency circuit | ≤ 9 kVA freely definable |
| Emergency power switchover | automatic (in under 20 milliseconds) |
Intelligent control
- 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 (power limits)
Recycling
The 100% recycling is carried out by the manufacturer itself. There, the complete battery is returned to its raw material cycle. The transport of the battery to be discarded back to the manufacturer in Stabio/CH is to be borne by the customer. Despite complete recycling by the manufacturer, INOBAT in Switzerland charges an advance recycling or disposal fee per battery. Our sales partners can provide you with the costs for this.
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.

Extension options
If the storage demand increases, another battery can be added at any time (even years later) without any problems. The storage capacity then increases by 9 kWh to 18 kWh total storage capacity. Both batteries can be operated with the three Victon AC inverters.
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.
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.
