Intelligent battery storage as a smart investment
Don't pay more for electricity than you need to. With a correctly sized battery storage system, you can use 100% of your own renewable electricity, secure your energy self-sufficiency and earn on the spot market as well.
Three power ranges of RA-100 cabinet battery storage systems cover applications in homes, communities, industry and the energy sector.

Professional battery energy storage system
Long service life
Extended 10-year warranty
Hi-Tech quality
LG NMC automotive cells
Scalable capacity
100 kWh – 2+ MWh
Sustainable solution
The circular economy in practice
Three benefits for you
Safety and performance for modern operations
At the heart of the system are industrial LG Automotive Tier 1 cells with NMC chemistry, manufactured in the EU. They meet the strictest automotive and safety standards (IEC 62660-1/2/3, ISO 12405, UN 38.3), which guarantees maximum safety and a long service life even in demanding operation.
The RA-100 BMS (Battery Management System) monitors the voltage, temperature and SoH of every cell individually — in real time, with data accessible via an API or web interface.
Modular cabinet system
In a single compact 225 × 60 × 80 cm cabinet, the RA-100 battery storage system offers 100 kWh of usable (net) capacity. It can be scaled to more than 2 MWh by adding further racks, without redesigning the system.
NMC chemistry delivers higher energy density and lower weight than LFP alternatives — more energy per square metre and per kilogram. Ideal for peak shaving, maximising PV utilisation, backup power or charging EV fleets.
European quality and return on investment
A storage system developed and manufactured in the Czech Republic from European components — no customs risk and guaranteed delivery. Local service and documentation, all in full compliance with EU legislation and CE standards.
An NZIA-ready product, eligible for subsidy programmes. Our warranty terms are backed by real data from cell-level monitoring.
A cheap competing system that you replace twice a decade will cost more in the long run than an RA-100 system with guaranteed performance!
Let us advise you and design the right battery system for 2026.

Choose a configuration and see your return on investment instantly
Select the RA-100 ULTRA, PLUS or ONE variant and adjust the electricity price to match your tariff. The calculator instantly recalculates the investment cost, annual savings, payback period and cash flow over the entire service life of the system.
Select a performance series:
Storage parameters:
Total energy throughput over 10 years
The amount of energy depends on operating intensity and thermal management.
The financial breakdown is based on the electricity price you set.
Battery state of health (SoH) over time
Prediction based on the parameters of LG Chem NMC Tier 1 Automotive cells.
Solid line = optimistic scenario, dashed line = conservative prediction.
Cash flow and return on investment
Cumulative benefit from purchase to net profit. The tooltip shows data for the selected variant, including the estimated residual value over time.
RA-100 ULTRA — an investment tool
The only variant designed for intensive daily operation. Liquid cooling, 1C, maximum ROI, predicted service life of 12–15 years.
How do we calculate the residual value of the system?
Prediction: Based on LG Chem NMC Tier 1 Automotive parameters. We continuously refine it based on data from real-world installations.
ROI calculation: Does not include installation, grid connection or service costs. Prices excl. VAT.
Why choose 1PS TECHNOLOGY
We understand batteries. That is what sets us apart.
Expertise guarantee

We are experts in battery systems. We insist on technical correctness and demonstrable economic payback.
Modularity and TCO
