C&I Rooftop (10–30 kW): Office / Clinic / Supermarket

Who it’s for: Small-to-mid commercial buildings that need three-phase supply, seamless backup for IT/POS, and TOU bill savings.

Componente	Recommended	Why
PV array	12–30 kW on 2–3 MPPTs (2 strings/MPPT)	Covers daytime base load; handles mixed roof aspects
HV battery	15–30 kWh (dual HV ports supported)	Shaves evening peaks; rides through short outages
Backup bus	POS, lighting, networking, cashier PCs	Keeps operations online (UPS ≤20 ms)

Risultato: Sales & IT stay online during brownouts; TOU scheduling moves energy from off-peak to peak; zero-export available if the DSO requires.

Three-phase balance checklist:

Distribute single-phase sub-circuits across L1/L2/L3
Keep high-inrush motors (compressors) on non-backup side
Verify export limit readings before handover (screenshot)

“Two grid dips this week—checkout systems never rebooted.” — Facility Manager

H2-10k-30k-hybrid-inverter-application-C&I Rooftop

EV-Ready Villa / Boutique Hotel: HVAC + Night Peak Shaving

Who it’s for: Villas or small hotels with three-phase HVAC/heat pump and EV charging, aiming for comfort + lower bills.

Why it fits: Three-phase hybrid output + high-voltage battery handles evening peaks; UPS transfer ≤20 ms protects lighting/IT from flicker.

Suggested setup:

PV 15–25 kW across 2–3 MPPTs (split S/E/W)
Battery 20–30 kWh; reserve SOC 25–30% for outages
EV charger and HVAC placed on non-backup branch

Simple TOU plan (code style):

Charge (off-peak):   00:00–05:00
Discharge (peak):    18:00–22:00
Reserve SOC:         25%
Export Limit:        0 W (if required)

Installer notes:

Balance single-phase sub-loads across L1/L2/L3
Leave backup bus for lights, IT, security, elevators (if small)
Save screenshots of grid profile and export-limit for records

H2-10k-30k-hybrid-inverter-application-EV-Ready Villa

Apartment Building Common Areas: Night Security & Cost Control

Who it’s for: Multi-unit residential buildings needing quiet, seamless backup for corridors, lobby IT, and security—plus lower common-area bills.

Why H2-10k~30k fits: Three-phase hybrid output matches building services; dual HV battery ports scale from ~20–40 kWh; transfer ≤20 ms keeps lights/CCTV steady; noise <50 dBA suits indoor electrical rooms.

Subsystem	Typical power	Backup?	Note
Corridor & stairwell LEDs	300–800 W	Yes	No flicker during dips (UPS ≤20 ms)
CCTV + access control	50–120 W	Yes	24/7 continuity for security
Lobby/concierge IT	150–300 W	Yes	Routers, PCs, intercoms stay online
Water booster / elevator	kW-class	No	Leave on non-backup (high inrush)

Energy plan (simple):

PV daytime:      PV → Corridors/Lobby IT; surplus → Battery
Evening peak:    Battery → Corridors/CCTV (18:00–23:00)
Night buffer:    Reserve SOC 25–30% for late-night security
Maintenance:     Download monthly report; review alarms

Commissioning essentials:

Balance single-phase branches across L1/L2/L3 to reduce neutral loading.
Move essential circuits (LEDs/CCTV/IT) to the backup panel; label clearly.
Run a 2-minute outage test; confirm transfer time and load priority.

Recommended PV: 12–24 kW on 2–3 MPPTs; Battery: 20–40 kWh (dual HV ports).
Keep motors (pumps/elevators) on non-backup; schedule starts outside evening peaks.
Save screenshots of final parameters and monthly kWh report for board records.

“Two outages this month—corridors stayed lit and cameras never dropped.” — Building Manager

Domande frequenti

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

How do I choose the right inverter size (10k / 12k / 15k / 20k / 25k / 30k)?

Quick rule: Size the inverter by your peak daytime load e roof PV potential, not just the meter rating.

Site type	Typical peak load	Suggested inverter	PV array	Battery (evening 2–4h)
Small clinic / store	6–9 kW	10–12 kW	8–12 kW	10–15 kWh
Villa w/ heat pump	10–14 kW	15–20 kW	12–18 kW	15–20 kWh
Workshop / small factory	15–24 kW	20–25 kW	18–30 kW	20–30 kWh
Large retail / EV-ready	22–30 kW	25–30 kW	24–36 kW	25–40 kWh

Rules of thumb:

PV size ≈ 1.2–1.5 × average daytime load (roof & policy permitting).
Battery kWh ≈ evening peak kW × hours + 15–25% reserve.
Put EV charger / heavy motors on the non-backup side.

Checklist before you lock the size:

List top 5 loads you must keep during outages (backup bus).
Confirm roof orientations for 2–3 MPPT distribution.
Check local limits (export cap / phase balance / DNSP rules).

How does backup work and what wiring rules matter most?

Transfer time: ≤20 ms (datasheet also describes UPS 10 ms capability). Use backup for essential loads that must not reboot.

Model class	Recommended AC breaker
10–20 kW	50 A
25–30 kW	63 A

Grid/backup neutrals: In AU/NZ system diagrams, grid-side N and backup-side N are common; PE at the BACK-UP port is not connected. Follow local codes.

Balance single-phase loads across L1/L2/L3; keep high-inrush devices off backup.
Use 10–16 mm² AC cable (16 mm² recommended) and 8 mm² additional ground as guided.
Confirm LED/app status after a simulated grid-off test.

What can I actually do in the app day-to-day (without touching wiring)?

At a glance: See live PV, battery SOC, export power, and each phase’s load. Get alerts if something trips or a setting changes.

Everyday tasks you’ll use most:

Switch working modes: Self-Use / Backup / Time-of-Use.
Set a Reserve SOC (e.g., 25–30%) for evening outages.
Turn Zero-Export on/off if your utility requires it.
Check yesterday’s energy report and monthly trend.
Run a firmware update when prompted (one tap, no site visit).

Simple TOU schedule (example):

Charge (off-peak):   00:00–05:00
Discharge (peak):    18:00–22:00
Reserve SOC:         25%
Export Limit:        0 W (if policy needs it)

Pro tip: Share a “viewer” role with your client or manager so they can see the dashboard and bills-savings graph without changing settings.

How should I size PV strings and the HV battery for H2-10k~30k?

PV side: Max 1000 Vdc; MPPT 180–900 V; up to 3 MPPTs with 2 strings/MPPT. DC input currents 40/40/40 A allow modern high-current strings.

Rule of thumb: Aim for mid-window MPPT voltage (~500–750 V) for winter mornings; ensure string Voc(@ Tmin) stays <= 1000 V.

Example:
Panel Voc(stc)=49 V; TempCoeffVoc=-0.28%/°C; Tmin=-10°C
Voc(@-10°C)=49×[1+0.0028×(25-(-10))]≈53.8 V
Max series ≈ floor(1000/53.8)=18 modules/string

Battery side: LiFePO₄ 180–800 V; dual ports; max charge/discharge 2×50 A. Use CAN/RS485 BMS mapping for accurate SOC and safe curves.

Supports ~150% DC oversizing to boost yield in low-irradiance hours.
Supports three-phase voltage imbalance and fast battery charge/discharge.

How do I commission and monitor (app, grid profile, Volt-Var/Volt-Watt)?

Install the Elekeeper app (formerly eSAJ Home); choose Overseas Node; bind device by SN via Bluetooth.
Select country/grid profile (e.g., AS4777_A/B/C for AU) and save protection parameters.
Connect Wi-Fi/Ethernet/4G module for cloud; monitor via app or eSolar web.

Working modes: Self-consumption, Backup (with reserve SOC), Time-of-Use scheduling.

Power quality: Fixed PF/Var, Volt-Watt e Volt-Var per AS/NZS 4777.2 / DNSP presets. Review after firmware updates.

Simple TOU example:
Charge (off-peak): 00:00–05:00
Discharge (peak): 18:00–22:00
Reserve SOC: 25%
Export Limit: 0 W if required by utility
