Victron MPPT solar controllers offer a diverse range of products suitable for industrial, mining, marine, caravan and RV applications. A testament to Victron quality and reliability is the Victron 5 year product warranty.
Victron also offers the widest range of quality MPPT solar controllers in the market. The smaller 75/10 and 75/15 products are ideally suited to 12 and 24 volt systems that employ low cost 250 watt class "grid tie" panels. The 75 volt open circuit rating can also handle up to 3 x "12 volt" style panels in series for those who wish to retain existing panels.
The higher power 100/15, 100/30 and 100/50 products can take advantage of stacking two 260 watt class panels in series/parallel arrays for 12 and 24 volt systems. The higher open circuit voltage 150/35, 45, 60, 70, 85 and 100 models can handle up to 3 series panels in a series/parallel array.
The table below outlines the expected midday charge current into 12, 24 and 48 volt batteries for each controller with typical grid tie style solar panels. We are using a .7 power factor to derate the panel for lying flat and for temperature. Nominal 13, 26 and 52 volts were used in the calculations for battery voltage. Multiply the amps by about 6 to get an approximate idea of amp-hours generated per day. The "S" designates panels in a string and the "P" designates parallel. Actual panel output power will vary pending panel inclination, temperature, lattitude and season.

So called 12 volt panels can readily be used with the lower power controllers. Note that all panels connected to a single controller must be of the same model. In selection of the appropriate controller, the following should be taken into account.
- The number of panels in series times the panel Voc must not exceed the controllar Voc rating. The panel Voc for the lowest temperature operation should be used.
