Comparison of Conversol 5KW Off Grid Inverters-48V Battery

Direct Comparison of the best selling Conversol 5KW Off Grid Inverters

In this brief article we put together the key characteristics of two very popular solar inverters / chargers. The Conversol MKS II (2nd generation) is compared with the VMII 5kW off-grid inverter. Both devices output a pure sinewave voltage of 230VAC with selectable charging current from 10Amp to 80Amp. Voltacon integrated the latest MPPT algorithm on each unit with 99% efficiency. Technically that means a more accurate tracking of the PV power at any time with minium loss of power less than 1%.

Solar Panel Configuration – Example

Here, we recommend the wiring connection of solar panels with power rating from 250W to 315W

The minimum requirement of solar panels is 4 in series for the 5kW inverters with MPPT window 120-450V.

Minimum Power: 1 String of 4 panels in series (4 panels).

Full Power 2 string of 7 panels in series (14 Panels)

The above number is only a suggestion, other arrangements are also possible

The inverters are available from our official online solar shops please visit https://voltaconsolar.com

We also offer free of any obligation design services for off-grid solar photovoltaic systems.
