Textiles have heavy tax on.... 50% i think... solar not... for sure not 200% and as long as nothing is stock... why get your order just send to china over a third person? I cant afford a full system right now, so i build it step by step on a hybrid inverter plattform, 5kw, can link more boxes if needed. First add pv panels till over capacity, then add batteries, sun out, my Eskom bill drops just with panels connected. The box mixes the input with panels preferred. Garage runs on 2 300w panels and 300ah batteries off grid. Feeds fridge, internet routers, irrigation computer and garage door... never dropped below 50% capacity during winter, so never really cycles the batteries. Already now, batteries full at 11 from what the fridge used during the night. Sommer not even here... i will increase my panel capacity till i can run lights and AC during day time, with some battery backup for the veg and mother tent on 18/6. Mother tent runs on 150watts, the veg on 480w. I like the idea of solar powered indoor weed.. at least not nuclear like now
