Where This Model Fits Best

Use these scenarios to decide whether this model belongs on the shortlist before quote approval.

Urban Home Office: Quiet Backup for Work & Study

Who it’s for: Apartments or townhouses that need a silent backup for laptops, Wi-Fi, lights, and a fridge while working from home.

Why H2-5k~12k fits: Single-phase hybrid design, wall-mount IP65, low-voltage battery compatibility (40–60 V). Fan noise is low, suitable for indoor utility corners.

Suggested backup pack (example):

Load	Power	Hours/day
LED lighting (2–4 rooms)	120–200 W	4–6 h
Wi-Fi router + CCTV	25–45 W	24 h
Laptop / small PC	60–120 W	6–10 h
Fridge (inverter type)	90–150 W avg	24 h (duty)

3 quick steps:

Move essential sockets to the BACK-UP sub-circuit; label clearly.
Set a reserve SOC (e.g., 25–30%) so evening outages still have power.
Run a 2-minute outage test; confirm seamless transfer and load order.

Suburban House with TOU Tariffs: Cut Bills with Simple Scheduling

Who it’s for: Detached houses with 5–10 kW PV looking to shift energy from cheap night rates to the evening peak.

Typical setup: PV 5–10 kW on 2 MPPTs; battery 8–15 kWh (low-voltage pack); backup branch for lights, IT, and a fridge.

How savings happen (simple plan):

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

2 MPPTs handle east/west or south split roofs cleanly.
Use the app to adjust times each season as daylight shifts.
Keep heavy appliances (oven, large compressor) on non-backup.

Component	Recommended	Reason
PV array	5–10 kW	Covers daytime base load + charges battery
Battery	8–15 kWh	2–4 h peak shaving
Mode	Self-Use + TOU	Automated schedule; easy to tweak

Tip: Check the app’s daily report; if the battery often sits full at noon, slightly extend peak discharge or increase evening loads like laundry.

Small Retail / Clinic (Single-Phase): Keep Sales & IT Online

Who it’s for: Street-level shops, clinics, or cafés that run POS, lights, a small fridge, and basic IT—wanting steady service during short grid issues.

Recommended kit:

PV 6–10 kW split across 2 MPPTs (east/west or south split)
Battery 10–16 kWh for evening hours
Backup branch: POS, lighting, router/CCTV, small freezer

Energy flow (typical day):

Time block	Flow	Note
Morning–Afternoon	PV → Loads; surplus → Battery	Covers base load while open
Evening	Battery → POS, lights, IT	Smooth checkout during peak
Outage	Seamless backup output	No reboot on POS/router

Quick continuity checklist:

Label backup vs non-backup circuits at the board.
Keep high inrush appliances (big compressor, ovens) on non-backup.
Run a 10-minute test with the site open; check card terminals and printers.

FAQ for Technical Review

Use these questions to resolve monitoring, warranty, compatibility, and procurement concerns before approval.

How do I choose between H1, H2, and H2 LV?

Start with phase, battery path, and backup scope. H1 is usually the single-phase starting point, H2 covers higher-output hybrid paths, and H2 LV is the better fit when low-voltage battery architecture is part of the decision.

What battery and backup details should be confirmed before approval?

Confirm battery voltage path, backup expectation, and whether the project needs zero-export or time-of-use control. Those three points usually determine whether the shortlist is technically safe before the commercial quote moves forward.

When should I ask for meter, accessory, or compatibility review?

Ask before internal approval when the system needs export control, smart metering, monitoring accessories, or battery matching. Compatibility questions are much cheaper to solve before the buyer locks the model list.

Which file should I open first for a hybrid project?

Use the datasheet to confirm phase, PV range, battery path, and backup basics. Move into the user manual or quick guide when the installer needs detailed wiring, commissioning, or operating-mode review.

What should I include in the request if I need pricing or model guidance?

Send the project type, phase, battery requirement, destination market, and expected quantity. If the buyer is comparing multiple backup strategies, include the critical load expectation so the model recommendation stays aligned with the use case.
