German energy storage system company Tesvolt is to supply a 2.68mWh lithium-ion decentralised off-grid storage system to provide an African project with emergency power.
The 3.3 MW solar power plant and energy storage system (ESS) will act as a mini-grid during power cuts for water pumps in an agricultural project in Rwanda’s Eastern Province.
The ESS will store excess power from the PV power plant to be used during regular blackouts in Rwanda, which occur three or four times a day for between five and 45 minutes.
Simon Schandert, director of engineering at Tesvolt, said: “Only very powerful off-grid storage systems can supply the necessary emergency power several times per day, and there are only a few storage systems on the market which meet these requirements.”
Tesvolt is set to supply 134 fully assembled lithium storage systems for the 44 water pumps.
Tesvolt offers scalable storage systems up to 1mWh in six different size categories, with capacities ranging from 10 to 60 kWh.
Tesvolt will be introducing its storage systems at Intersolar Europe in Munich this week at exhibition booth 550 in hall B1.
