Conversol S2 Off-Grid Inverter - 5kVA, 48V, DUO MPPT Charger

Availability: In stock


Conversol s built in two MPP trackers and enhanced with solar charger and AC charger capability. DC Input terminals for 48V battery banks and pure sinewave output at 230VAC.


Conversol 5KVA/5kW Dual MPPT Solar Inverters.

Ultra Fast Battery Charging

After the successful development of the renowned 5kVA MPPT off grid inverter which is connected to a single string of photovoltaics, Voltacon Solar has put in full production one of the fastest off grid inverters in the market. The solar inverter is equipped with two dc inputs for two strings of solar panels. Each PV input has a max power of 3000W which offers an incredible photovoltaic power of 6000W per inverter.

Using two independent MPPT (maximum power point tracking) algorithms, the inverters offers ultra fast battery charging at 120A only from the solar panels. The combined charging current from solar and external source (diesel generator or national grid) can reach 180A !!!

Our solar experts developed a special DC combiner box with surge protection, dc-fuses and isolators.

Two Independent PV Inputs

The exceptional value for money makes the 5kVA (5000Watt) 48Vdc autonomous inverter the preferred solution for the most demanding solar applications.

  • Pure sine wave AC output
  • Integrated 2 strings of MPPT solar charge controller
  • Adjustable input voltage range for home appliances and personal computers
  • Adjustable high power charging current
  • Configurable AC/Solar input priority via LCD setting
  • It is compatible to mains voltage or other AC power generator
  • Auto restart while AC is recovering
  • Overload over current and short circuit protection.
 The dual feed of solar power offers freedon to choose panels from different make, one MPPT input can be connected to one particular brand of photovoltaics and the secondary input coould be used with another brand.

Customer Reviews

off grid solar kit 5kw parallel Review by Ciprian Bogdan
I am using this inverter with a parallel kit (Single Phase 10kVA), it runs smoothly all my loads even my air condition (summer/winter time).

It would be nice to have a bigger display but the free WatchPower runs from the computer is really easy to use.

Superior Charger Review by Peter Tayloe
One of the faster chargers in the market, 2x MPPT inputs at 60A each, i do not even need back up generator. I am using 6000W of solar panels though (Posted on 4/28/2017)
OFF GRID SYSTEM in Wales Review by Steve WARD
Very easy to set up , we had plenty of support from VOLTACON. THANKS (Posted on 2/20/2017)
Ben fatto e ottimo funzionamento Review by Giuseppe
Ottimo inverter di rete sia sotto l'aspetto della conversione MPPT e come Inverter di rete, ottimo sistema di ricarica batterie. (Posted on 6/2/2016)
