SV MAX 3000VA
2.4 kW · 24V
The SV MAX 3000VA is the off-grid specialist: a 3,000 VA / 2,400 W pure-sine inverter-charger built for sites where the grid is absent or barely present. A 3:1 surge ratio starts pumps and compressors that flatten lesser inverters, and the transfer switch flips in ≤10 ms in UPS mode.
It accepts lead-acid, gel, flooded and lithium banks at 24 V or 48 V, offers an optional built-in MPPT or PWM solar charger (30–60 A), and provides a generator auto-start signal so remote sites refuel the batteries without anyone on site.

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 (60 A solar + mains charger), 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 or 48 V (model-dependent) 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
At 24 V use two SV 12-200 AGM in series; at 48 V use four in series or a 48 V lithium pack. Match the bank to the unit's configured bus voltage exactly. 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
With the built-in MPPT option: up to 1,600 W of PV at 24 V or 3,200 W at 48 V, string voltage within 30–150 VDC (24 V) or 60–150 VDC (48 V) — shorter strings than the EDGE/PRO range. 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
Generator auto-start
Wire the auto-start signal to the generator controller and set the battery voltage thresholds so the genset starts on low battery and stops when absorption completes.
- 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.
