Quick Answers
Frequently asked questions
Answers drawn from the specification tables and datasheets above — ask our sales engineers for anything model-specific.
What battery chemistry do COTECH storage systems use, and how long do the cells last?
All systems use LiFePO4 (lithium iron phosphate) cells. Residential systems are rated to ≥10,000 cycles with ≥95% usable depth of discharge; the container ESS uses LFP 280/314 Ah cells rated to ≥8,000 cycles.
What capacities does the ESS Pro home storage system offer?
ESS Pro stacks from 5.12 to 30.72 kWh per tower with a 6, 8 or 11 kW hybrid inverter, parallels to roughly 120 kWh, and switches to backup power in under 10 ms.
How large is the COTECH container energy storage system?
The 20-ft liquid-cooled LFP container delivers 3.44 or 5.02 MWh per unit for utility-scale and large C&I projects, with liquid cooling holding the cell temperature spread to ΔT ≤3 °C.
Is there a storage option for apartments and balconies?
Yes. Balcony storage kits combine 300 – 1000 W of panels with a micro-inverter and a 1.5 – 2.5 kWh battery, installing plug-and-play on a balcony rail.
What safety systems are built into COTECH energy storage?
Multi-level safety: a smart BMS, gas detection, aerosol fire suppression and explosion venting.
