Salt battery storage systems optimised for small PV systems

1-phase storage with 7 kWh

Sustainability costs more than the mass product, as we all know. So does good design. And rightly so. Because the conscious and clean use of resources is costly – from the procurement of raw materials to production and recycling. And so is a natural enclosure made of pure solid wood. In the battery business, this is an unusual combination. So if you like to do without plastic and follow your good taste, this battery storage unit will serve you on all levels. What if ecology and style come together? Then you have found your perfect battery storage unit!

innovenergy® offers you an naturally chic salt-based eco-storage system for your PV system:

  • 1 x 3 kVA inverter power (230 V)
  • 7 kWh storage capacity - not expandable
  • Maximisation of your own consumption through intelligent control
  • Monitoring of the power situation and and energy analysis via smartphone app or internet browser
  • plug & store - turnkey solution with easy installation

The salidomo® ECO is an AC-coupled 1-phase salt battery storage system for smaller PV systems. The system works with all PV inverters. The installed battery inverter capacity is 3 kVA. The battery storage capacity of the salidomo® ECO corresponds to 7.7 kWh – up to 80 % usable in normal operation, up to 100 % in emergency power operation.

In Switzerland, 1-phase systems up to 3.6 kVA (16 A) inverter power may be installed. For more than 3.6 kVA feed-in power, 3-phase systems must be used. With an inverter output of 3 kVA, the salidomo® ECO is below the maximum limit and is therefore approved for Switzerland. Our sales partners will be happy to advise you.

Definition of emergency power

Emergency power/UPS
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/UPS
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® ECO is always capable of emergency power supply via a socket connected to the battery system. In the event of a power failure, the battery can continue to be used until it is empty.

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 (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.

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.
