SV EDGE 4.2K
4.2 kW · 24V
The SV EDGE 4.2K is the hybrid of the 24 V range: alongside standard off-grid operation it is grid-connect capable, feeding excess solar into the grid at 98% efficiency with a power factor above 0.99 — or running zero-export where feed-in is not permitted.
With 4.2 kW continuous output, a 120 A charger and up to 5,000 W of PV input, it suits a larger villa or small office that wants maximum solar self-consumption with battery backup as the second layer.

Professional installation
Site preparation
- Mount indoors or under shade in a dry, ventilated space — keep at least 300 mm clearance on all sides for airflow and service access.
- Fix to a solid masonry wall or rigid frame at eye level; never on plasterboard alone.
- Provision a DC battery breaker or fuse rated ~1.25× the maximum charge/discharge current (120 A), plus a PV string isolator and an AC output breaker.
- Keep battery cable runs short (under 3 m where possible) and use correctly sized lugs — voltage drop on the battery side is the most common cause of nuisance shutdowns.
Safety first
- This is a 24 V battery-bus system — only connect a battery bank of matching nominal voltage.
- PV strings carry lethal DC voltage in daylight. Never connect or disconnect PV connectors under load.
- Torque all terminals to specification and re-check after the first week of operation — thermal cycling loosens DC lugs.
- Installation must be carried out by a qualified electrician in accordance with local wiring regulations.
Commissioning checklist
- Confirm battery voltage, PV string Voc and AC input readings on the display match your meter.
- Verify charge current settings match the battery manufacturer's limits.
- Simulate a grid failure and confirm the transfer to battery is clean under a real load.
- Record serial number and settings — Sole Verde support will ask for both.
Installation sequence
- 1
Mount the unit
Mark the bracket, drill and anchor, then hang and lock the inverter. Confirm it sits plumb and the fans are unobstructed.
- 2
Connect the battery bank
Use two SV 12-200 AGM batteries in series for the 24 V bank, or a 24 V lithium pack with BMS communication. Connect through the DC breaker with the breaker open, observing polarity — reverse polarity is the single most damaging installation error.
- 3
Connect the PV array
Up to 5,000 W of PV through the 60–500 VDC MPPT window. Verify string open-circuit voltage with a multimeter before plugging in — it must sit inside the MPPT window at the coldest expected morning.
- 4
Wire the AC side
Land grid/generator input and load output on separate breakers with correct phase, neutral and earth. Bond the chassis earth terminal to the building earth.
- 5
Grid-connection settings
If exporting to the grid, set the grid standard and export limit in the menu to match the local utility's requirements — grid feed-in requires utility approval in most markets.
- 6
Power up in sequence
Close battery DC first, then PV, then AC. Set battery type, charge current and output priority in the menu before applying load.
