I have a kings 120 watt solar panel on the roof running thru a MPPT kings controller. Supacentre is not bullshitting their specs like a lot of ebay sellers, it is 120 watts and it is MPPT and it is a fair price. Solar panels… 1 square metre of direct sun light = 1000 watts. At 18% efficiency a typical 1 x1 metre solar panel will max out at 180 watts. Remember this when you buy off ebay.
My kings setup runs my second shitty lead acid under bonnet battery with VSR which powers a crappy aldi 40 lt fridge all year round, with room to spare for the occasional travel buddy morning tea. Weekday driven about 50k to work and back😀
