The High-Consumption Smart Home

Who it’s for: Large modern homes with three-phase power, high energy demands (pool pumps, multiple air conditioners, home offices), and an EV, seeking maximum energy independence and a premium, integrated solution.

What HS3 changes: It’s a powerful central energy hub. The system handles large PV arrays (up to 15 kWp) and heavy loads, while the optional 11 kW EV charger integrates seamlessly. Its large, expandable battery (up to 40 kWh) can power the entire home through evenings and multi-day outages.

Typical high-demand loads (example):

Load Power (W) Priority
Central Air Conditioning 3000–5000 Run on solar/grid
EV Charger Up to 11,000 Charge with surplus solar
Pool Pump 800–1500 Run on solar
Kitchen & Essentials 500–2500 Alimentazione di emergenza UPS

How it runs (Self-Use + EV + Backup Mode):

Daytime:      PV → Power all loads; surplus → Charge EV; extra → Charge Battery
Evening:      Battery → Power entire home
Grid Outage:  Battery → Seamlessly power essential circuits (<20ms switch)
Set Reserve:  Keep Battery SOC at 25% for outage protection

Sizing guide (for reference):

  • A 15 kWh battery system (3 modules) can comfortably cover a high-use evening (6-8 kWh) while retaining ample backup power.
  • A 25 kWh system (5 modules) provides true multi-day energy security for the whole home.

“It’s true energy independence. The HS3 runs our whole house, charges the car, and we barely notice when the grid goes down. The single, sleek unit is a huge bonus.”

Small Commercial & Workshop Resilience

Who it’s for: Small businesses, workshops, or agricultural operations with three-phase machinery and critical systems (like refrigeration, servers, or automated equipment) that need to cut daytime energy costs and ensure operational continuity.

What HS3 changes: It offsets significant daytime electricity costs by powering machinery directly from solar. The 100% phase imbalance support is crucial for workshops where loads are not evenly distributed. The large backup capacity ensures that critical operations (e.g., cold storage, IT systems) continue during grid outages, preventing financial loss.

Critical business loads (example):

Load Power (W) Put on BACK-UP?
Office Server & Network 200–350 Yes
Refrigeration / Cold Room 1500–3000 Yes
Lighting & Security 300–600 Yes
Heavy Machinery 5000–10000+ No (keep on grid)

How it runs (Backup & Self-Use Mode):

Daytime:      PV → Power all loads (office + machinery); surplus → Battery
Grid Outage:  Battery → Instantly powers backup circuit (office, refrigeration)
Evening:      Battery → Powers essential overnight loads (servers, security)
Set Reserve:  Keep Battery SOC at 50% minimum for business-hour backup

Runtime guide (for reference):

  • A 10 kWh battery pack can run a 2 kW critical load for over 4 hours, bridging most common power cuts.
  • A 25 kWh system (5 modules) provides extended resilience for a full working day’s essential operations.

“We can’t afford downtime. The HS3 has already saved us from two outages, keeping our cold storage and servers running perfectly. The reduction in our daytime power bill is a massive bonus.”

Domande frequenti

Trova le risposte alle domande più frequenti sui nostri prodotti e servizi

How do I size HS3 (5–12 kW) for a typical three-phase home or small business?

Use this quick path to match inverter, PV, and battery.

  1. Estimate peak load: add the kW of big appliances likely to run together (e.g., AC 3 kW + oven 2 kW + pumps 1 kW ≈ 6 kW).
  2. Pick inverter power: choose the next HS3 size up from peak. For the example, select HS3-6k.
  3. Size the PV array: match model limits (see table). Aim for 0.9–1.2× inverter kW in many markets.
  4. Choose battery modules: each BU3 pack is 5.0 kWh nominal, about 4.5 kWh usable. Start with 2–3 packs for evening loads.
HS3 model 5k 6k 8k 10k 12k
Max PV @ STC 10 kW 12 kW 12 kW 15 kW 15 kW
MPPT / Max DC V 2 MPPT, 180–900 V; 1000 V max
Battery scalability Up to 8× BU3 modules (stack or multiple stacks)
Example: A shop with 22 kWh evening use → 5 packs ≈ 22.5 kWh usable. Pair with HS3-8k and ~8–10 kW PV.
What backup power can HS3 deliver, and how do I estimate runtime?

Backup output is three-phase with short surge support. Use this table to plan essential loads.

HS3 model Rated backup (W) 60 s surge (VA) Voltage / Freq Output THDv
5k 5000 7500 220/230/240 V; 50/60 Hz <3%
6k 6000 9000 — —
8k 8000 12000 — —
10k 10000 15000 — —
12k 12000 15000 — —

Quick runtime math (approx.):

Runtime (h) ≈ Usable battery (kWh) ÷ Load (kW)

  • 3× BU3 packs ≈ 13.5 kWh usable → ~2.2 h at a steady 6 kW.
  • 5× BU3 packs ≈ 22.5 kWh usable → ~1.9 h at 12 kW (shorter at high surge).
How do I monitor the system and access data?

You get local indicators plus app/portal tools.

  • Front LEDs: show PV, grid, battery, backup, COM, and EV charger status at a glance.
  • Elekeeper App: Bluetooth + Wi-Fi/Ethernet or 4G (model-dependent) for live PV, load, grid and battery data.
  • Smart meter (DTSU666): RS485 link enables accurate import/export and advanced features.

Installer checklist

  1. Wire the meter CTs correctly (arrows toward inverter/on-grid).
  2. Verify RS485 polarity (A/B) at the meter and inverter terminals.
  3. Commission via App; confirm data refresh and phase mapping.

For long runs (>20 m) between inverter and meter, enable the 120 Ω termination as noted in the manual.

What installation environment and layout do installers usually follow?

In sintesi

  • IP65 enclosure — indoor or outdoor.
  • Cooling: natural convection; keep clearances and mount vertically.
  • Noise: <35 dBA — very quiet in utility areas.
  • Altitude/Temp: up to 3000 m; −30 to +50 °C (power derates >45 °C).
  • Size/Weight (inverter): 450×695×170 mm; ~34 kg.
Do Don’t
Install on a solid wall, vertical orientation; keep vents clear. Don’t tilt forward/horizontal; avoid direct sun causing heat derate.
Maintain service space around the unit and stacks. Don’t place near sprinklers or in bedrooms/bathrooms.
Three-phase basics: 3L+N+PE, 220/380–240/415 V; 50/60 Hz as per local grid code.
What protections are built in, and what do they mean for daily use?

Protection is integrated on both DC and AC sides to meet common grid codes.

Protection What it helps with
Anti-islanding (AFD) Stops backfeeding a dead grid during outages.
AFCI Detects DC arc faults on PV strings.
DC/AC surge, Type II Reduces damage risk from lightning/overvoltage.
RCMU / leakage monitor Monitors residual current; supports RCD coordination.

The system also supports 100% three-phase voltage imbalance and keeps THDv <3% on backup for sensitive loads.
