yes as somebody else said, it's easy when cooking to go over 3.6 rate. but it's only for half and hour in the evening. we are looking at a Wind Turbine and another inverter, so the two combined will give us greater than 3.6 rate. but we're not doing that for that reason, it's like 15p per half hour if we go to 5kw by accident for a bit at tea time when the kids are home from school. but a larger inverter capacity will solve that. we only cook with Electricity also. so if you have a gas hob you wont exceed it unless you put microwave on and kettle and oven. and then you wont be drawing from the grid for long.

yes it's amazing, it forms part of the decision making algorithm. it's not 100% accurate here, manchester, sometimes it's under and sometimes its over. so had to compensate with other weather api's, which gives a more accurate reading for our location. it just allows you to utilise the off peak tariff more effectively. off peak tariff on its own just doesnt work out for us. but with an EV and solar panels, and battery ESS = massive savings each day. and effortless when it's all tied together/joined up with software APIs. we do use a lot of electricity here. only the boiler is Gas. so we dont cook with gas. and during summer we use the immersion heater for warming the cylinder. (because we have solar, it's cheaper than gas.)

yes rolled out my own control/monitoring. i couldnt find any other app that does what i wanted. it's all joined up now, all integrated.. so batteries charge to a sufficient level off-peak, based on the prediction for sunlight tomorrow/later today. otherwise you'd have to keep checking BBC weather yourself and judging it, and hoping, and never forgetting to check. we're busy enough. it could be done with almost any solar energy storage system, any inverter pretty much. we were sold the luxpower so that's what i had to work with.

hi i've got the luxpower 3.6 with pylontech batteries works fine i turned off the chinese internet port. and i just access it locally. so if solar prediction from the met office API is low, medium or high for my home's needs, it'll charge the batteries high, medium or low, on the off peak from Bulb ev tariff. the luxpower then during the day does everything it can to prevent importing from the grid. it's got a CT clamp on the CU tails, and knows when the grid is importing/feeding in and it tries to invert as much as it can from solar and/or battery to feed the loads instead of pulling from the grid. when the loads calm down, the inverter calsm down to. within a second or two. it's pretty good
