The Modern Eco-Home
Who it’s for: New-build or renovated homes with three-phase power, aiming for maximum energy self-sufficiency, future-proofed for an EV, and a clean, minimalist aesthetic.
Daily energy flow (example):
| Time of Day | Primary Energy Source | Key Activity |
|---|---|---|
| Morning (09:00-12:00) | Solar PV | Power home loads, start charging battery |
| Afternoon (12:00-16:00) | Solar PV (Surplus) | Charge EV with 100% green energy |
| Evening (18:00-22:00) | Battery Storage | Run kitchen, lighting, entertainment |
| Grid Outage | Battery (UPS Mode) | Seamless power to essential circuits |
How it runs (Self-Use + EV Smart Charging):
Priority 1: Power the home with solar. Priority 2: Use surplus solar to charge the EV. Priority 3: Use any remaining solar to charge the battery. Priority 4: Export to grid (if allowed/desired). Evening: Discharge battery to power the home.
Sizing guide (for reference):
- A 10 kWh battery system (2 modules) covers typical evening use and provides a solid backup reserve.
- With an 8 kWp PV array, the system can easily cover daily home use (~15 kWh) and provide a significant charge to an EV (~20-25 kWh) on a sunny day.
“The design is fantastic. One slim unit in the garage handles everything. We run the house and charge the car almost entirely from the sun.”
Small Business & Office Resilience
Who it’s for: Small businesses, workshops, or home offices with three-phase power that need to reduce daytime energy costs and ensure uninterrupted operation of critical equipment like servers, POS systems, and security.
Critical business loads (example):
| Load | Power (W) | Put on BACK-UP? |
|---|---|---|
| Office Server & Network | 200–350 | Yes |
| Workstations (2-3 staff) | 300–500 | Yes |
| Security System (CCTV) | 50–100 | Yes |
| Workshop Machinery | 1000–3000+ | No (keep on grid) |
How it runs (Backup & Self-Use Mode):
Daytime: PV → Power all loads (office + workshop); surplus → Battery Grid Outage: Battery → Instantly powers backup circuit (office/security) Evening: Battery → Powers any overnight loads (servers, security) Set Reserve: Keep Battery SOC at 40% minimum for business-hour backup
Runtime guide (for reference):
- A 5 kWh battery pack can run a 600 W critical office load for over 7 hours, easily bridging most power cuts.
- A 15 kWh system (3 modules) provides extended multi-day resilience for essential equipment.
“We had a blackout last week and didn’t even notice until the streetlights were out. The server, computers, and phones kept running without a single glitch.”

How much power can the HS3-3/4K deliver on-grid and in backup?
Quick view
| Model | Rated AC (on-grid) | Backup apparent power (continuous) | Peak backup (60 s) |
| HS3-3K-T2 | 3,000 W | 3,300 VA | 6,000 VA |
| HS3-4K-T2 | 4,000 W | 4,400 VA | 8,000 VA |
- Connection: 3-phase, 3L+N+PE; typical grid 230/400 V, 50/60 Hz.
- Backup port supplies critical loads separately from on-grid loads.
- THD on backup output <3% (linear load), suitable for common household and small commercial equipment.
How do I size the battery stack for HS3-3/4K projects?
Modular approach: Each BU3 pack is 5.0 kWh rated (~4.5 kWh usable). One inverter supports up to 8 packs (max ~36 kWh usable).
| Packs | Usable energy (approx.) | Example use case (typical) |
| 1 | ~4.5 kWh | Short outages; lights, router, small fridge for ~4–6 h |
| 2–3 | ~9–13.5 kWh | Whole-home essentials overnight or a small office till morning |
| 4–8 | ~18–36 kWh | Longer autonomy; multi-day load shifting (depends on usage) |
- Max 3 batteries per vertical stack.
- For 4–8 batteries, use multiple stacks plus the BC3 battery combiner box.
- Keep ~0.5 m between stacks for cabling.
Commissioning will detect insulation or communication faults and report codes in the app; resolve before handover.
What space and environment do I need for installation?
- Install vertically; avoid forward tilt.
- Allow ~30 cm clearance on sides/top for airflow.
- Permissible tilt: ≤3° back, ≤2° sideways.
- HS3 inverter: ~450 × 695 × 170 mm; ~34 kg.
- BU3 battery (per module): ~695 × 420/370 × 170 mm.
- Indoor/outdoor, IP65 enclosure.
- Operating up to 50 °C (derating above ~45 °C).
- Natural convection; typical noise <35 dBA.
- Altitude up to 3000 m; non-condensing 5–95% RH.
How do monitoring and communications work for HS3-3/4K?
- Bluetooth (BLE) for nearby setup via the Elekeeper app.
- W models: Wi-Fi + Ethernet (LAN). G models: 4G SIM slot.
- Ports: RS485 (meter/EMS), CAN (battery/EMS), dry contacts (DO/DI).
- Real-time PV, battery, grid and backup load power.
- Historical energy charts, alarms, and firmware status.
- Chint DTSU666 (3-phase), 100 A per line, RS485.
- CT options available (80/100/250 A scenarios).
- Power up; check LEDs.
- Connect via Elekeeper (BLE), then bind Wi-Fi/Ethernet/4G.
- Verify meter RS485 and CT direction.
Which grid-safety and protection functions are built in?
- Anti-islanding (AFD) and arc-fault (AFCI) protection integrated.
- DC & AC surge protection integrated; RCMU embedded.
- External RCD (if required by local code): Type A or B, ≥300 mA.
- Recommended AC breaker between grid and inverter: ≥63 A.
- System connection: separate GRID and BACKUP ports; 3L+N+PE.
Wiring reminders
- Use the supplied 3-phase meter via RS485 for accurate control.
