German battery producer VoltStorage has unveiled a 50 kWh vanadium redox movement battery designed to optimize self-consumption in business and industrial PV methods

VoltStorage VDIUM C50 is an AC-coupled battery with a system voltage of 48 V. The producer affords a 20-year guarantee on the electrolyte and guarantees that it degrades beneath 0.3% per yr.

It additionally affords a five-year guarantee on the facility electronics. The brand new product is available in a typical container and weighs 2 tons with out electrolyte. When it’s full, it weighs 6.5 tons. Electrolyte pumps and energy electronics devour 40 W in standby mode.

The system may be cascaded in a 10-unit configuration and attain a complete capability of 500 kWh. The discharge capability is 9 kW. At full energy, the system is empty after six hours.

The producer says that the system, because of the redox expertise, can obtain a depth of discharge of 100%. When charging the system, operators ought to plan six hours for 80% and 9 hours for 100%. At 10 kW, the charging energy is lower than the discharging energy.

VoltStorage additionally says the system has an IP54 safety ranking. It’s endorsed to put in it in an out of doors surroundings.
