この製品が、さまざまな実生活での場面でどのように活用できるかをご覧ください

The High-Consumption Smart Home

対象者： 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):

読み込み	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	UPSバックアップ

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

対象者： 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):

読み込み	Power (W)	Put on BACK-UP?
Office Server & Network	200–350	はい
Refrigeration / Cold Room	1500–3000	はい
Lighting & Security	300–600	はい
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.”

よくある質問

当社の製品やサービスに関するよくある質問とその回答をご覧ください

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.

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).
Pick inverter power: choose the next HS3 size up from peak. For the example, select HS3-6k.
Size the PV array: match model limits (see table). Aim for 0.9–1.2× inverter kW in many markets.
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)

例： 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

Wire the meter CTs correctly (arrows toward inverter/on-grid).
Verify RS485 polarity (A/B) at the meter and inverter terminals.
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?

At a glance

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.

What does Sunriver Electric include to make HS3 projects easier to quote and deploy?
