Solar EV Charging & Home Backup

Who it’s for: Homeowners with an Electric Vehicle who want to maximise clean energy use, charge their car with sunshine, and secure essential power during outages.

What HS3 changes: The optional integrated 7.4 kW EV charger works seamlessly with the solar and battery. The system intelligently directs surplus solar to the car, while the UPS function keeps critical loads online if the grid fails.

Key loads & priorities (example):

Load Power (W) Priority
EV Charger Up to 7,400 1 (when surplus PV is high)
Home Office & Fridge 200–400 2 (always on, UPS backup)
General Household 500–2000 3 (covered by PV/battery)

How it runs (Self-Use + EV Mode):

Sunny Day:    PV → House; surplus → EV Charger; extra → Battery
Cloudy Day:   PV → House; Battery tops up loads
Evening:      Battery → House; (optional: top up EV from battery/grid)
Grid Outage:  Battery → Backup circuit (lights, fridge, office)

Charging guide (for reference):

  • A 10 kWh battery system can add ~35-45 km of range to an EV overnight from stored energy alone.
  • With 6 kW of PV panels, a full sunny day can provide over 30 kWh of energy—enough for a full charge on many standard-range EVs.

Do/Don’t for the backup branch:

Put on BACK-UP Keep on non-backup
Lights, router, fridge, home office, security EV Charger, AC unit, oven, water heater

“I drive on sunshine. The app prioritises charging the car when the sun is out, and the battery handles the house at night. The integrated charger makes it so clean.”

Cut Evening Bills & Beat Peak Tariffs

Who it’s for: Families with high energy use after sunset who want to slash their electricity bills by avoiding expensive peak-hour grid tariffs.

What HS3 changes: It stores free solar energy from the day and automatically deploys it during the evening peak, cutting grid reliance when power is most expensive. The all-in-one design keeps the garage or utility room tidy.

Typical evening loads (example):

Load Power (W) Energy Use (4h)
Kitchen (cooking, microwave) 1200–2000 ~1.5 kWh
Entertainment (TV, console) 200–400 ~1.0 kWh
Lighting & General Use 150–300 ~0.8 kWh
Total Evening Use – ~3.3 kWh

How it runs (Time-of-Use Mode):

Daytime (Off-Peak):  PV → House; surplus → Battery
17:00–21:00 (Peak):  Battery → House; avoid grid import
Night (Off-Peak):    Grid → House; (optional: charge battery on cheap tariff)

Sizing guide (for reference):

  • A 5 kWh battery pack (4.5 kWh usable) easily covers a typical 3–4 kWh evening peak, making the home self-sufficient when grid costs are highest.
  • A 10 kWh system provides a larger buffer for heavy-use days or cloudy weather.

“Our power bill is down 70%. The HS3 stores solar during the day and runs the house for free every evening. It’s completely automatic.”

Domande frequenti

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

What documents ship with HS3-3k~6k projects?

Short answer: every shipment comes with a clean document set so installers can move fast.

Included by default

  • Datasheet & user manual (digital + QR code on carton)
  • Quick installation guide (printed)
  • Basic compliance pack: CE/RCM marks visible on rating label; DoC on request
Monitoring access Elekeeper App (Wi-Fi/Ethernet/4G as model-specific)
Meter kit Three-phase smart meter + CTs (model/country dependent)

Need a customized pack (e.g., test report bundle or localized manual)? Tell us the destination market and we’ll attach the right files.

Tip: share your meter distance from inverter; if >20 m we advise enabling the 120 Ω termination for RS485 runs.

How do we quote and prepare HS3 shipments for distributors?

Process: simple, fast, predictable.

  1. Quote — send model qty + port; we reply with FOB/EXW price tiers and lead time in 1–2 business days.
  2. Packing — export cartons with corner guards; palletized, stretch-wrapped; QR code links to manual.
  3. Pre-ship check — serial list (CSV), carton count, net/gross weight, and packing photos for your records.
Carton labeling Model / SN / handling icons / QR to docs
Compliance marks CE, RoHS; RCM for AU/NZ versions

“Pre-ship photo set saved us a site revisit — the meter kit was confirmed before dispatch.” — Installer, Rotterdam

Can you help match batteries and size the stack for HS3 projects?

Yes. HS3 pairs with BU3 5.0 kWh LiFePO₄ modules. We’ll size stacks for your load profile and tariff windows.

Per module

  • Rated energy: 5.0 kWh
  • Usable energy: 4.5 kWh
  • Voltage window: 380–500 V

Per inverter

  • Battery packs per HS3: up to 8
  • Max per stack: 3 high (use combiner for more)
  • Total usable (8×): up to ~36 kWh

What we need: daily kWh, desired backup hours, and space constraints (wall/ground mount). We’ll return 1–2 stack options with wiring sketches.

How quiet is the HS3 system and where should I install it?

Noise: ≤35 dBA with natural convection cooling — suitable for utility rooms and garages.

Placement checklist

  • Indoor or outdoor (IP65). Keep dry and out of direct sun.
  • Vertical mount; leave ~30 cm clearance around for airflow.
  • Avoid habitable rooms for the battery stack; keep away from heat sources.
Operating temp (Pro models) -30 °C to +50 °C (derate >45 °C)
Ingress protection IP65 (inverter & battery)

For garages, mount above potential flood level; keep clear of driveways.

What protections are built in, and what does the installer still need to add?

Built-in protections include anti-islanding (AFD), AFCI, DC & AC surge protection, and residual current monitoring (RCMU). The system also supervises ground faults and insulation status.

THDi (grid) <3%
Overvoltage category II (DC), III (AC)
Altitudine 0–3000 m

Installer adds

  • AC breaker ≥63 A between grid and inverter
  • RCD only if required by local code (typ. ≥300 mA)
  • Earthing per national standards

A bundled smart meter (DTSU666 class 1) enables export control and accurate site monitoring when required by the utility.

How do I monitor and commission HS3 on site?

Commissioning and monitoring are done via the Elekeeper App (BLE for proximity; Wi-Fi/Ethernet/4G for remote).

  1. Power up: BATTERY switch → DC switch → press START ~3 s until LEDs light.
  2. Check LEDs: GRID/SOLAR/BACK-UP solid means normal; COM solid = cloud connected.
  3. App steps: scan SN → set grid code → pair meter → set battery pack count → verify live flows.

Live data you’ll see

  • PV, battery SOC, grid import/export, and backup load power
  • Alarms with plain-text codes for faster troubleshooting
  • Historical energy charts for performance reviews
Can HS3 work with an existing string inverter (AC-coupled) and provide backup?

Yes. HS3 supports AC-coupling with one or more PV inverters. Use the PV-side CT input to measure the external inverter output and coordinate charging.

Wiring pointers

  • Grid CT on utility feed; PV CT on legacy inverter feed
  • Essential loads on BACK-UP terminal
  • Shared neutral per regional rules (AU/NZ note)

Site benefits

  • Re-use existing PV; add storage and backup
  • App shows combined PV, battery, and load
  • Zero re-roof: minimal DC rewiring

For long RS485 runs to the meter (>20 m), enable line termination for stable comms.
