Suburban House with Heat Pump & Laundry (TOU Savings + Backup)

Who it’s for: Detached homes that want lower evening bills and seamless backup for lights/IT while running a heat pump and daily laundry.

Component Recommended Why
PV array 6–10 kW (2 MPPT, split E/W or S) Covers daytime base load + charges battery
Battery stack 10–16 kWh usable 2–4 h evening peak shaving + outage buffer
Backup branch LEDs, router/CCTV, work PC, fridge Seamless transfer (UPS-class) without reboots

Simple TOU schedule (example):

Charge (off-peak):  00:00–05:00
Daytime:            PV → Loads; surplus → Battery
Discharge (peak):   18:00–22:00
Reserve SOC:        25–30%

Installer checklist:

  • Put heat pump/washer on non-backup; keep backup for steady loads.
  • Label backup sockets clearly to avoid accidental heavy tools usage.
  • Run a 2-minute outage test at sunset to verify switchover and runtime.

“Evening bills dropped and lights never flicker during short cuts.”

HS2-5k-10k-all-in-one-energy-storage-solution-Suburban House
EV-Ready Home: Peak Shaving + Off-Peak Charging (Single-Phase)

Who it’s for: Homes that want to control evening bills while charging an EV at night. EV charger stays on non-backup; house essentials sit on backup.

House vs EV — simple split:

Circuit What’s on it Reason
BACK-UP LEDs, router/CCTV, work PC, fridge No flicker/reboot during grid blips
NON-BACKUP EV charger (10–16 A), oven, AC compressor Avoid high inrush on transfer

Daily schedule (example):

House battery:   Charge 00:00–05:00; Discharge 18:00–22:00; Reserve SOC 25–30%
EV charging:     Start 00:30 @ 10–16 A (off-peak); stop by 05:30
Notes:           Keep EV on non-backup; label sockets to avoid mix-ups
Sizing hint: If evening essential load ≈ 0.5–0.8 kW for 4 h, choose ~8–12 kWh usable. Add modules later if EV use increases household peaks.

Rural Café / Clinic (Unstable Grid): Quiet Backup Without a Genset

Who it’s for: Sites with frequent dips/short cuts that still need lights, Wi-Fi/EMR, and a small fridge to keep operating calmly.

Time Energy flow Note
Morning–Afternoon PV → Loads; surplus → Battery Quiet operation, indoor-friendly
Evening Battery → Lights/IT No genset noise/fumes
Grid outage UPS-class transfer POS/EMR stays online

Wiring quick path:

  1. Move LEDs, router/EMR PC, small fridge to BACK-UP.
  2. Keep coffee machines/ovens on non-backup (high inrush).
  3. Mark the board and run a 2-minute outage test for staff training.

Noise & placement: Locate the stack in a back room; low audible noise suits patient areas and small dining rooms.

“Two sags this week — lights and router never blinked; service stayed calm.”

Frequently Asked Questions

Find answers to common questions about our products and services

How should I plan the BACK-UP sub-board for HS2-5~10K sites?

Goal: keep essentials alive during short outages without nuisance trips or reboots.

Put on BACK-UP Typical load Why
IT & networking Wi-Fi/CCTV 30–60 W No reboot on switchover ≤10 ms
Lighting (LED) 150–250 W (3–5 rooms) Low inrush, safety/operations
Office/retail devices Laptop/POS 60–150 W Avoids data loss
Fridge (inverter type) 90–150 W avg Food safety

Backup power window (model examples):

  • HS2-5K: 5,000 VA (peak 10,000 VA for 60 s)
  • HS2-8K: 8,000 VA (peak 16,000 VA for 60 s)
  • HS2-10K: 10,000 VA (peak 16,500 VA for 60 s)

Output distortion on linear loads: <3% THDv.

  1. Move selected circuits to the dedicated BACK-UP terminals; label clearly.
  2. Keep high-inrush devices (EV charger, big oven, large compressors) on non-backup.
  3. Set a reserve SoC (e.g., 25–30%) and perform a 2-minute grid-off test before handover.

“POS and lights stayed up; customers didn’t notice the grid dip.”

What’s the quickest commissioning workflow with the app?

Target: first-time power flow on day one, with settings captured for records.

  1. Install comm module; power AC breaker; press Start to wake the system.
  2. Open the mobile app → Remote Configuration → Bluetooth → bind by inverter SN tail.
  3. Select country & grid code; confirm date/time and phase sequence.
  4. Pick a working mode: Self-Use, Time-of-Use, or Back-up; set reserve SoC (e.g., 25–30%).
  5. Join Wi-Fi/Ethernet/4G; create the plant; check live PV → Load → Battery → Grid.

5-minute handover checklist:

  • Screenshot final grid profile, SoC reserve, and TOU windows
  • Run a grid-off test (no flicker/reboot on BACK-UP)
  • Share “viewer” access with the owner/store manager

Simple TOU template (example):

Charge (off-peak):  00:00–05:00
Daytime:            PV → Loads; surplus → Battery
Discharge (peak):   18:00–22:00
Reserve SoC:        25–30%
How do I expand from 10 kWh to 25 kWh later without headaches?

Capacity map (usable): 2→5 modules ≈ 9.0 / 13.5 / 18.0 / 22.5 kWh. Plan space and conduits for the final stack from day one.

Upgrade workflow:

  1. Schedule downtime; isolate AC & PV; power down per manual.
  2. Add battery module(s); secure with locking brackets; install side covers.
  3. Reconnect COMM/power harness; power up; confirm new capacity in the app.
  4. Run a short charge/discharge to verify module reporting and balance.
  • Keep SoC of old/new modules within ±5–10% before coupling.
  • Maintain ventilation clearances (natural convection cooling).
  • Label stack height on the board to avoid future overloading of the wall/base.
What protection & compliance features are built in?
Característica What it does Why it matters
RCMU (integrated) Residual current monitoring RCD optional only if local code requires
Surge protection Integrated DC & AC SPD Protects against transient events
Anti-islanding Grid-safety disconnection Utility compliance
AFCI / RSD (optional) Arc detection / rapid shut-down Extra DC-side safety
Environment & build: IP65, natural-convection cooling; operating −10~50 °C (derate >45 °C); altitude up to 4000 m (derate >3000 m); noise <30 dBA.

Standards snapshot: EN 62109-1/2, EN 50549, IEC 62116/61727, AS 4777.2, VDE-AR-N 4105, and more (see datasheet).

Grid quality: supports 100% three-phase voltage imbalance; Euro efficiency up to 97.6%.

What’s in the cartons, and how should I stage the install?

Typical contents (inverter + battery packages): plug-in GRID/BACK-UP connectors, PV connectors (HS2), smart meter + 3 CTs, COMM cables, mounting brackets, grounding cable, side covers, and printed/QR docs. Communication module may be included if ordered.

Staging checklist (saves time on site):

  • Mark wall/base positions with the provided template; confirm clearances for stack growth.
  • Pre-label BACK-UP vs non-backup circuits on the board.
  • Pre-run AC/PV/COMM conduits; prepare Wi-Fi SSID/password or Ethernet drop.
  • Lay out connectors by circuit (PV / BAT / GRID / BACK-UP) to avoid cross-wiring.
  • Plan a 2-minute outage test for handover.

Note: Use one external AC breaker per inverter (typical 63 A recommendation for HS2-5~10K). Type A or B RCD only if required by local code.
