What we deliver
SUMMERLAB SK supplies complete battery energy storage systems for manufacturing plants, logistics hubs, agricultural enterprises, data centres and EV charging operators. Every system is built on Tier-1 LFP cells with predictable degradation and a service life beyond 10 000 cycles.
We do not sell boxes off a shelf. We size the system against your consumption profile, tariff structure and existing generation, then deliver a turnkey solution with the documentation required for grid connection.
Product line
From a single all-in-one cabinet behind the meter to multi-megawatt containers on the distribution grid. Every unit ships factory-assembled and tested.
All-in-One C&I Cabinet
Compact all-in-one BESS cabinet for small and medium industrial sites. Combines PV, diesel genset and storage into one managed microgrid, factory-assembled and pre-commissioned.
Hybrid PV-ESS-Diesel Cabinet
Hybrid storage system for enterprises with on-site generation. Switches between grid and island mode in 10 ms, so sensitive production never notices an outage.
Industrial Cabinet
Industrial cabinet with precision liquid cooling that keeps the temperature spread between cells within 3 °C, protecting cycle life through hot summers.
Liquid-Cooled C&I Cabinet
The quietest cabinet in the series at 65 dB, certified for grid connection in 45 countries and started with a single touch in 40 seconds.
Liquid-Cooled C&I Cabinet
Integrated cabinet combining battery, BMS, EMS, PCS, liquid cooling and fire protection for commercial and industrial sites.
Transformer-Free Building Block
The most powerful cabinet in the series. Several blocks stack into a system beyond 1 MWh without a dedicated transformer.
20 ft Container
Containerised storage for large sites. Rack count is configured to the discharge duration the project requires.
Utility-Scale Container
All-in-One liquid-cooled container on 530 Ah LFP cells with a grid-forming PCS, built for utility-scale and weak-grid projects.
All-in-One Container
Turnkey 1 MW containerised system with Tier-1 LFP batteries in IP67 enclosures and four-level protection.
Integrated AC/DC 20 ft Container
Turnkey containerised storage with integrated power conversion, liquid-cooled LFP batteries and multi-level safety monitoring.
EV Supercharging Solution
Complete solution for EV hubs: storage removes the transformer bottleneck and delivers the power needed for fast charging without grid reconstruction.
Technology
Precision liquid loops hold the temperature spread between cells within 3–4 °C, so capacity does not collapse in summer and cycle life stays predictable.
Monitoring, early warning, alarm and intervention — with built-in suppression and precise localisation of the alarm source.
Battery, PCS, BMS, climate control and suppression ship factory-assembled in one enclosure. Cabinets parallel with cabinets, containers with containers.
Peak shaving, dynamic export limitation, genset and PV inverter control over Modbus TCP/RTU and MQTT, in one dashboard.
Utility-scale PCS forms the grid on its own, which suits island systems, weak grids and black-start requirements.
Grid-connection certification with the full documentation package for customs and the distribution system operator.
