There are growing concerns that ruZZia will once again target Ukraine’s energy infrastructure this autumn and winter. The best time to prepare is now. Let’s help Ukraine build a large reserve of high-capacity battery systems that can keep workshops, hospitals, and frontline units running when the power goes out.

Some of the most cost-effective solutions are:

⚡ 6 kWh portable power stations
1 kWh EcoFlow Delta 2 + 5 kWh golf cart or server rack battery

⚡ Expand existing power stations
Many EcoFlow and other brand power stations already in Ukraine can be upgraded with an external 5 kWh golf cart or server rack battery + custom connection cable.
The photo accompanying this post shows a 5 kWh golf cart battery supplied by Eyes on Ukraine, expanding an EcoFlow power station that was already in service.

⚡ Large stationary energy storage
10, 15, 20 or even 32 kWh batteries combined with a (solar) inverter provide reliable backup power for workshops, humanitarian facilities, and critical infrastructure.
Useful components:
• 5–20 kWh wall mounted batteries: eu.humsienk.com/products/48v-wall-mounted-lifepo4-battery-series?variant=52796627091735
• 32 kWh floor standing battery: docanpower.com/panda-52v-628ah-32kwh-prebuilt-pack
A great example of a solar inverter system powering a Ukrainian 3D-printing workshop.

Every battery built before winter is one less system that needs to be rushed in after the lights go out.
