How much space does it take and what does installation require?

About 2 m² of ground space, outdoors. The cabinet is IP54 rated and operates between −25 °C and +50 °C, so it needs no dedicated building or climate-controlled room — just a simple foundation and access for connection.

What maintenance does it need?

Minimal: the system is monitored online, and the BMS and EMS automatically manage balancing and temperature. We perform periodic checks included in the support contract, with local interventions from Câmpina.

What warranties do I get?

A 10-year warranty on the CATL battery cells, certified for 8,000 cycles at 0.5P, plus the manufacturer warranty on electronics. Installation and commissioning are guaranteed by us.

Can I expand capacity later?

Yes. Cabinets expand in parallel up to 20 units — you can start with 232 kWh and grow as consumption or tariffs justify it, without changing the existing infrastructure.

Does it work with my existing photovoltaic system?

Yes. The BESS integrates with existing PV installations: it stores surplus production instead of injecting it cheaply into the grid, and delivers it during high-tariff hours.

How it works

What is an industrial battery energy storage system (BESS)?

A BESS stores energy when it is cheap or in surplus and delivers it when it is expensive or unavailable. A single outdoor cabinet holds the battery, bidirectional inverter, BMS, EMS and liquid cooling — no dedicated technical room needed.

For companies this means three concrete things: arbitrage on day/night tariffs, shaving penalized consumption peaks, and automatic backup for processes that must not stop.

✓At night: charges at reduced tariff or from PV surplus

✓At consumption peaks: delivers energy and shaves penalized peaks

✓During outages: picks up critical loads in 8 ms (with STS)

Charging

At night on reduced tariff, or during the day from PV surplus.

Storage

CATL LFP cells with liquid cooling and per-module BMS.

Peak discharge

The EMS delivers energy when tariffs or consumption are high.

Automatic backup

On grid failure, it switches to battery in 8 ms (STS version).

Configurations and prices

Two standard turnkey configurations

Installed and commissioned by our own team. For any other capacity from 100 kWh upwards, we configure to order.

The configurations below are standard examples. For projects from 100 kWh upwards, capacity is configured based on the consumption profile, contracted power and economic goal.

Who is a BESS right for?

✓Companies with day/night differentiated tariffs

✓Consumers with penalized power peaks

✓Production that must not stop during outages

✓Businesses with existing PV that want arbitrage

Why CATL

CATL cells, not anonymous cells

CATL LFP technology is the industrial standard for stationary storage. The difference versus generic or NMC cells shows in safety, lifespan and traceability.

How companies use it

Tariff arbitrage

Charge at night on a reduced tariff and consume during expensive hours — the difference becomes monthly savings.

Peak shaving

The EMS limits power peaks drawn from the grid and avoids excess-demand penalties.

Backup for production

Critical lines switch to battery in milliseconds — no scrap and no process stops.

Business case

What one unit produces in a day

A 254 kWh cabinet, at one cycle per day: you charge at night on a reduced tariff (red bars) and discharge at peak, when energy is expensive (green bars). The difference, in lei, is the daily arbitrage.

The system charges when energy is cheap and uses it when energy — or contracted power — becomes expensive.

Separate savings stream

Plus: peak shaving

Beyond arbitrage, the system limits the power peak drawn from the grid: it discharges the battery exactly during maximum-consumption moments, so you do not exceed your contracted power.

✓Reduces contracted-power overrun penalties

✓Can allow a lower contracted grid capacity

This is a savings stream distinct from arbitrage and is quantified separately, during the project analysis, based on your contracted power and peak history.

Peak shaving: grid draw capped at peak

Without storage, grid consumption follows the peaks (blue line). With storage, the system discharges the battery exactly at peak and caps the power drawn from the grid (green line). The blue area is the peak that is shaved.

FAQ

Frequently asked questions about industrial storage

From three cumulative sources: arbitrage (charge cheap at night, consume during expensive hours), shaving penalized power peaks, and avoiding losses during grid outages. At current tariffs, standard configurations typically pay back in 4–6 years.
