SV PRO 5500W

5.5 kW · 48V

The SV PRO 5500W moves the PRO platform onto the 48 V bus that serious systems are built on. One unit delivers 5.5 kW continuous with an 11,000 VA surge rating; up to nine can be paralleled for 49.5 kW — so the same hardware serves a villa today and a workshop next year.

It takes up to 6,200 W of PV per unit, restarts lithium banks automatically after a protection event, and holds output voltage within ±5% — tight enough for sensitive lab and medical equipment.

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 (100 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 48 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. 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. 2

    Connect the battery bank

    Pair with 51.2 V LiFePO4 storage — one or more Lithium Battery 5KWH or 11.8KWH modules in parallel with BMS communication connected. Connect through the DC breaker with the breaker open, observing polarity — reverse polarity is the single most damaging installation error.

  3. 3

    Connect the PV array

    Up to 6,200 W of PV per unit across 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. 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. 5

    Parallel configuration (multi-unit systems)

    Install paralleled units side by side with equal-length battery cables, link the parallel communication cables, and set each unit's parallel ID before first power-up.

  6. 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.

Alarm (yellow light)

1Fan self-testShow fix

The cooling fan is running its start-up check.

  1. Clears on its own.
  2. If it keeps appearing, clean dust from the fan and vents.
2Over temperature / NTC disconnectShow fix

The inverter is running hotter than its safe limit, or the temperature sensor lost contact.

  1. Switch the inverter off and let it cool for 30 minutes.
  2. Leave at least 20 cm clear on every side.
  3. Never install in a sealed cupboard or in direct sunlight.
3Battery over voltageShow fix

Charging voltage is set too high for the battery, or the BMS link is missing.

  1. Check the charge settings: lithium 56.4–57.6 V, AGM 12 V float 13.6–13.8 V.
  2. Confirm the battery type is set correctly in the inverter menu.
  3. On lithium, check the BMS communication cable is seated.
4Low battery voltageShow fix

The bank has been drawn down further than it should be.

  1. Reduce the load now.
  2. Charge from solar or AC.
  3. Never take AGM below 50 % — repeated deep discharge permanently shortens its life.
7OverloadShow fix

More load is connected than the inverter is rated for. The alarm beeps twice a second.

  1. Switch off heavy appliances immediately — iron, water pump, washing machine.
  2. Add the wattage of everything running and compare it with the inverter's rating.
  3. Reconnect one appliance at a time, smallest first.
10Output power deratingShow fix

The inverter is deliberately reducing output to protect itself, usually from heat.

  1. Reduce the load.
  2. Improve ventilation.
  3. It recovers by itself once cooler.
15Low PV (solar) inputShow fix

Little or no power is arriving from the panels.

  1. Clean the panels.
  2. Check for shade from trees, walls or a water tank.
  3. Check the MC4 connectors are fully clicked together.
  4. Normal in cloud, or early morning and late afternoon.
16AC input voltage too highShow fix

The grid or generator is supplying above the accepted range.

  1. On a generator, check the AVR.
  2. On grid, wait for the supply to stabilise.
65PV current signal faultyShow fix

The inverter cannot read the solar current correctly.

  1. Check the PV cable connections for damage.
  2. Contact support if it persists.
BPBattery not connectedShow fix

The inverter cannot see the battery bank at all.

  1. Check the cables, the fuse and the terminals for corrosion.
  2. On lithium, press the battery's ON button.
  3. Check the DC breaker is closed.
EQBattery equalisationShow fix

A scheduled conditioning charge is running.

  1. Normal for AGM — let it finish.
  2. Disable equalisation in settings when using lithium.

Fault (red light)

F1Fan self-check failedShow fix

The cooling fan did not start correctly.

  1. Switch off and check the fan spins freely.

Never open the inverter yourself — it voids the warranty and carries a real risk of shock. Contact a Sole Verde verified technician.

F2Over temperature / NTC disconnectShow fix

The unit reached a dangerous temperature, or the sensor failed.

  1. Switch off at once and let it cool for an hour.
  2. Check ventilation and clearance.
  3. If the temperature is normal but the fault stays, the sensor needs a technician.

Never open the inverter yourself — it voids the warranty and carries a real risk of shock. Contact a Sole Verde verified technician.

F3Battery over voltage (serious)Show fix

F5AC output short circuitShow fix

A short was detected on the output wiring or an appliance.

  1. Switch off and disconnect every appliance.
  2. Check the output wiring for damage.

  2. If it stays low with nothing connected, it needs service.

Never open the inverter yourself — it voids the warranty and carries a real risk of shock. Contact a Sole Verde verified technician.

59PV input over voltageShow fix

Too many panels in series — string voltage exceeds the inverter's limit.

  1. Disconnect the solar panels immediately.
  2. Recalculate string open-circuit voltage at the coldest expected temperature.
  3. Rewire the strings shorter before reconnecting.

Never open the inverter yourself — it voids the warranty and carries a real risk of shock. Contact a Sole Verde verified technician.
