Our solar & battery systems, from a small home to a factory
We have chosen to specialise in KSTAR: a single, well-engineered platform that scales from a compact home battery up to industrial storage. One system we know deeply, matched to your needs.
There are dozens of solar and battery brands on the market. We made a deliberate choice: specialise in KSTAR, partnered with CATL and EVE for its LFP cells, rather than juggle many brands.

When a project genuinely calls for something different, we will tell you honestly.
Below is the range, organised by scale, so you can see roughly where your property fits before we prepare a proper study.
Scale 1
Home
Houses & apartments. Inverters 3.68β10 kW, storage 5.1β40.8 kWh, modular.
See home systems β Scale 2Large home / small business
Villas with heavy loads, small commercial. 50 kW inverter + ~100 kWh cabinet.
See 50kW class β Scale 3Commercial & industrial

All-in-one hybrid systems for houses and apartments. A KSTAR inverter paired with modular CATL or EVE LFP battery packs (BluE-Pack 5.1, 5.12 kWh each), so storage can grow with your needs. IP65 rated for outdoor installation.
| Model | Inverter | Storage (modular) | Best for |
|---|---|---|---|
| BluE-S 3680D | 3.68 kW single-phase | 5.1 β 20.4 kWh | Smaller homes, apartments |
| BluE-S 5000D | 5 kW single-phase | 5.1 β 20.4 kWh | Typical family homes |
| BluE-S 10KT | 10 kW three-phase | 10.2 β 40.8 kWh | Larger homes, three-phase supply |
CATL or EVE LFP cells Β· modular expansion in 5.12 kWh steps Β· three-phase backup output with fast on/off-grid switching Β· EMS and app monitoring included.
2 Β· Large homes & small commercial β KSTAR 50kW class
When a standard home battery is not enough, villas with pools, heat pumps and EV charging, or small businesses, move up to a 50kW hybrid inverter (KAC50DP) paired with a 100kWh-class battery cabinet (BC100DE, 102.4 kWh, CATL LFP, integrated BMS and air conditioning).
| Building block | Spec | Best for |
|---|---|---|
| KAC50DP inverter | 50 kW three-phase hybrid | High-demand homes, small commercial |
| BC100DE cabinet | 102.4 kWh, CATL LFP | Meaningful daily storage & backup |
3 Β· Commercial & industrial β KSTAR BluePulse
For businesses and industrial sites: modular cabinets that run in parallel to reach the capacity a site needs, for self-consumption, peak shaving and critical backup.
| Cabinet | Capacity | Notes |
|---|---|---|
| BC100DE | 102.4 kWh | Entry C&I / large homes |
| BC197DE | 197 kWh | Commercial loads |
| BC215DE | 215 kWh Β· 125 kW | IP54, C4 anti-corrosion, up to 20 units in parallel |

How we match a system to you
The table above is a starting map, not a menu to pick from blindly. The right system depends on your electricity bills, your supply and fuse size, your roof, and whether you want self-consumption, backup, or both. That is what our free assessment works out, and then we specify the exact KSTAR configuration that fits.
Common questions about our range
It is a deliberate specialisation. One well-engineered platform, with CATL or EVE LFP battery cells, that we know deeply: faster installation, fewer surprises, and proper long-term support. When a project genuinely needs different equipment, we tell you honestly.
Yes. The residential range is modular: BluE-Pack batteries add in 5.12 kWh steps, up to 20.4 kWh on single-phase systems and 40.8 kWh on the three-phase 10KT. We design with expansion in mind so a later upgrade is straightforward.
Yes. Across the range, from home packs to industrial cabinets, the cells are lithium iron phosphate (LFP) from CATL or EVE, chosen for thermal stability and long cycle life.
It depends on your electricity bills, your supply and fuse size, your roof and whether you want backup. Start with our free assessment, or check the supply limits with our kW guide, and we will point you to the right scale honestly.
