Hi. I m lucky enough to have my batteries on float by midday, and i.m looking at using a 1 KW immersion element to utilise my spare energy. I recently watched a video from victron which suggests that I can use a ve direct tx cable to control a load output relay from my 100/50 smart solar mppt. I need one which will switch my inverter feed into the 240 v element through my Sterling 1500 watt inverter until it pulls the batteries down to the(heaters) disconnect voltage(or thermostat kicks in). This will run in parallel with a flat plate collector heating water directly from the sun. Has anybody done this?,and could you post a link to the appropriate relay/contactor. I believe the ve port puts out 5volts. I have 1500 watts of solar running through 2x victron mppts into 1400Ah of agms in sunny southern Portugal. Tia. Steve.
