The Pylontech OPTIM US A300-HY is a commercial and industrial energy storage system (BESS) with integrated hybrid inverters, built on lithium iron phosphate (LFP) chemistry. Supplied as a ready-to-connect outdoor cabinet, it combines battery modules, PCS inverters, thermal management and fire protection for peak-shaving, energy time-shift, self-consumption and long-duration backup applications.
Why choose the A300 HY?
- Modular and scalable: from 8 to 21 modules of
15.68 kWh per cabinet, i.e. 125.44 to 329.28 kWh per cabinet, with
power scaling through cabinets in parallel for large projects.
- Integrated hybrid inverters (PCS) Solis
S6-EH3P(30-50)K-H: directly usable 400 Vac three-phase output,
with built-in PV input and back-up port.
- Durable LFP chemistry: DoD 95 %, round-trip
efficiency 95 % (@0.5 C), design service life
15 years and more.
- Designed for outdoor use: IP55 cabinet,
industrial air conditioning + forced cooling, operating range
−40 to +55 °C, C3H anti-corrosion treatment.
- Reinforced safety: aerosol fire suppression,
gas, smoke and temperature detectors, EPO and electrical protections.

Configurations & capacities
Each cabinet is configured to order according to the number of
HM5A180F modules (15.68 kWh each). Two battery-string architectures are
available:

By multiplying cabinets, the system covers the commercial and
industrial range of 172 to 1565 kWh and 50 to 500 kW
(up to 10 inverters of 50 kW), for peak shaving, energy time-shift,
self-consumption and long-duration backup.
