Hi there all, just a quick question regarding wiring up 4x100Ah 12V batteries for 24V Inverters. Which is going to be better for the batteries life expectancy and charging? a) 2 sets of batteries in Parallel then joined in Series: or b) 2 sets of batteries in Series then joined in Parallel: From a cabling / resistance point, it seems that option a) will have an extra cable (5) where option b) has less cables (4) interconnecting the batteries. The batteries are all the same i.e. 100Ah 12V, and hopefully no internal imbalances. Which is going to be better for the batteries life expectancy and charging? Thanks all!

The unit is boxed, including all original Manuals, Stickers, Screws, Mounting plate, 3 CT's, Dongle, Temperature Probe, BMS Cable, and a 18mm Shutterboard Back Board.

For Sale: Sunsynk 12Kw 3 Phase Inverter + SunSynk Dongle for R58,500 incl VAT We purchase this for a client, and after completing the installation it turns out that when they thought they had 3 phase power, they in fact now have a Red / White / Blue phase in their house which is each showing 230V. It used to be full three phase, but apparently the cable is damaged, so as a quick fix Eskom has bridged the White phase to the Red and Blue in the distribution board (disconnected the incoming Red and Blue - see picture). As a result this unit will not sync with the grid as it is not 3 phase (voltage between the Red / White and Blue is 0V and not 380V). We removed the unit as it would not sync with the grid and installed a Sunsynk 16Kw (single output feeding the house Red White and Blue) which is working perfectly. The Sunsynk 12Kw 3 Phase unit including SunSynk Dongle is for sale at R58,500 incl VAT.
