Application Scenarios

Discover how this product can be used in different real-world scenarios

Urban Homes with Frequent Power Cuts

Who it’s for: City apartments or townhouses with unstable grid or planned load-shedding.

Why H2 works here: UPS-grade switchover (≤10 ms) keeps lights, router, and fridge on; quiet hybrid design suits indoor walls.

Typical backup pack (example):

Load Power Hours
LED lighting (3–5 rooms) 200–300 W 4–6 h
Wi-Fi router + CCTV 30–50 W 24 h
Fridge (inverter type) 90–150 W avg 24 h (duty)

3 quick steps:

  1. Wire essential loads to the backup output terminals.
  2. Set a reserve SOC (e.g., 25–30%) to survive evening outages.
  3. Run a test outage to verify transfer and load priority.

“Outage came and went—TV didn’t even blink. The UPS timing is solid.” — Installer, Manila

Suburban Rooftop Self-Consumption with TOU Savings

Who it’s for: Detached houses with 3–6 kW PV aiming to cut bills using Time-of-Use (TOU) scheduling.

How savings happen: Charge battery off-peak at night → discharge during evening peak → daytime loads use PV first.

Component Recommended Reason
PV array 4–6 kW Covers daytime base load
Battery 7–10 kWh HV Enough for evening peak
Mode Self-Use + TOU Automated schedule

Sample TOU plan:

Charge: 00:00–05:00 (off-peak)
Discharge: 18:00–23:00 (peak)
Reserve SOC: 25%
Zero-export: Enabled 08:00–18:00 (policy-limited regions)

Review schedule quarterly as daylight hours shift.

  • Quiet operation for garage or utility room installations
  • App & web dashboards for daily/weekly savings review
  • Compatible with high-efficiency modules (182/210 mm)

Zero-Export Compliance for Restricted Grids

Who it’s for: Homes where utilities prohibit feed-in (e.g., strict residential policies in parts of SEA).

Compliance setup (summary):

  1. Install CT clamp on main line (arrow → grid)
  2. Connect smart meter via RS485; set unique address
  3. Enable Export Limit and set cap = 0 W in app

Household example: 5 kW PV + 7.5 kWh battery. Daytime loads powered by PV; surplus stored, not exported; evening peak served from battery.

Check What to verify
CT orientation Arrow points to grid; reverse if values are negative
RS485 wiring A/B lines not swapped; unique meter ID
App status Export power = 0 W during daylight
Note: Keep screenshots of “0 W export” as audit evidence for local utility checks.

Häufig gestellte Fragen

Find answers to common questions about our products and services

What batteries work best with the H2-3k~6k-S2?

Battery type: High-voltage lithium battery packs with BMS.

Recommended chemistry LiFePO₄ or NMC (with certified BMS)
Battery voltage window ≈ 85–450 V
Max charge/discharge current up to 30 A (model-dependent)
Comm protocols CAN / RS485 (BMS handshake)
Tip: Pick battery brands with verified CAN mapping for SAJ. This enables accurate SOC and safer charge curves.

Quick compatibility checklist:

  • BMS supports CAN/RS485 and exposes SOC/voltage correctly
  • Battery OCP/OVP thresholds align with inverter limits
  • Balanced pack; insulation & polarity check passed

Avoid mixing old and new modules in one pack; keep cable lengths equal; follow torque specs on HV connectors.

Can it keep loads running during blackouts?
Yes — built-in UPS switchover ≤10 ms. Lights, routers and other essentials stay on without reboot.

Suggested “essential loads” plan (example):

Load Rated power Daily hours
LED lighting (5 rooms) 250 W 5 h
Router + CCTV 40 W 24 h
Refrigerator (inverter type) 120 W avg 24 h (duty)

3-step setup:

  1. Wire “backup loads” to dedicated backup output terminals
  2. Set battery reserve SOC (e.g., 25–30%) for outages
  3. Test a manual grid cut to confirm transfer and priorities
Note: Motor loads with high inrush (e.g., pumps) may require soft-start or be excluded from backup circuit.
How does it coordinate PV, battery, and grid in daily use?

Working modes at a glance:

Mode Flow logic When to use
Self-Use PV → Load → Battery → Grid Maximize self-consumption
Time-of-Use Charge off-peak; discharge peak High tariff spread regions
Backup Hold SOC reserve for outages Unstable grids

Example TOU schedule (simple):

Charge: 00:00–05:00 (grid, off-peak)
Discharge to load: 18:00–23:00 (peak)
Reserve SOC: 25%
Zero-export: Enabled 08:00–18:00
Tip: Re-check schedule after season changes; evening peak shifts with daylight hours.
Can I limit or block export to the grid?

Yes. Pair the inverter with a compatible meter/CT to enable dynamic export control and 0-export.

Wiring steps (summary):

  1. Install CT clamp on incoming phase (arrow → grid)
  2. Connect meter via RS485; set correct baud and address
  3. Enable Export Limit in app; set cap (e.g., 0 W)

Common mistakes to avoid:

  • CT reversed → readings negative; fix orientation
  • Wrong RS485 A/B wiring → no data; swap A/B
  • Multiple meters on same bus without unique IDs

Config password (factory default) may be required for advanced settings. Change it after commissioning.

How do I monitor performance and commission the system?

Monitoring options:

  • LCD + LEDs for on-site status and quick faults
  • Mobile app for live power, SOC, and alarms
  • Web portal for reports and multi-site fleets
Ports CAN / RS485 / RS232
Connectivity Wi-Fi / Ethernet / 4G (stick/module)
Typical setup time 8–12 minutes after wiring

Commissioning quick path:

  1. Scan device SN → bind to site
  2. Select country/grid profile → verify frequency/voltage
  3. Run export limit wizard (if required)
Note: Save a screenshot of final parameters; it speeds up future audits and remote support.
