    Sense check on compatibility

    A friend is being suggested a solar Edge inverter for his system and has asked me if it sounds like a good fit. Could you make comment please. He has initailly 20 jinko jkm435n ( 435WSIC, 327WNOCI, 37.2 Voc, 30.33 Vpm, 10.78A), with space for ten more. Tigo TSA-A-O optimisers, on each panel...

    Octopus intelligent vs Go

    Lots to digest , thank you. Are the additional octopus controlled “cheap” periods @ 7.5p Any recommendations on a simple home charger that complies? Could I pick something up ( independent of car plugged in or needing charge) so I could switch my pool heater on in these “ cheap” periods? I have...

    Octopus intelligent vs Go

    I am currently on Octopus Go, with its 4 hrs of cheap electricity. I concentrate consumption to this time( 2 ev’s, pool heater, washing machine dishwasher etc) The period is not quite long enough for my needs. The “ Intelligent” tariff would be perfect (2p cheaper and for 6 hours), but there are...

    PV production routing

    thanks all i have plenty to read up on! my house has a few smart systems i've put in over time. i expect it is time to rationalise the lot! The Shelly system is looking interesting! Incidentally: could you tell me what pins 5&6 are for on me emlite ECA2 imp/exp meter please

    PV production routing

    Hi there I'm building a PV system (15Kw) and I want to be able to route the power, depending on production rate. so as I get close to' feed in' switch on say tumble dryer then car then pool heater etc. My system is based on Enphase equipment, apparently they make a " IQ router+", but I'm...

    E vehicle charging

    Gentlemen May I have a little guidance on ev charging please. both of my plug in hybrid cars have charge leads with a 13 amp plug on end and a 7pin car plug the other and they are interchangeable. 1 what form is the electricity that is presented to the car? 2 what does the box in...

    DIY solar install

    Hi Tony I'm experimenting with similar ideas, and practicing on an isolated system for my pool ( see my previous threads). what ive learnt so far is go for more panels. If you have the space double up. My 2.8 kw array peaks at 2.1 Kw and that only and hour or two, mid summer.

    Series or Parallel

    My inverter arrived, and testing started today! 4 x 200 ah batteries full and moderately sunny day for the 10, 235w panels My GSHO and circulation pump ran for 4 1/2 hours before the system did a low V shut down ( grid connection isolated for the duration of the test). So theoretical...

    Low tariff electricity to top up PV System

    My house needs around 65 Kw/h a day ( + some gas in the winter). The pool and cars are a large proportion of this. It seems to me swapping to a tariff with a very low night rate, but high day rate, then managing when the cars charge and pool heats makes would make a substantial saving. ( £5.5K...

    Heat pumps

    I experimented with that a little, and found in our cold climate the results disappointing. maybe my array sample was poor quality. i think a PV system with battery storage will be the most flexible. I have a 2.5 KW solar array, a 5kw hybrid inverter ( to allow for start ups), a heat pump and...

    Heat pumps

    Could we have a new sub group for heat pumps, ideally in green energy, although not renewable. I've got a couple of units one with an interesting application; the other, heating the pool, I'm trying to drive from solar. I think PV and heat pumps together could be an interesting subject. just an...

    Series or Parallel

    Many thanks, I'll do series. Might be able to squeeze an 11th panel on the roof. I went OTT with the inverter because I was concerned with the start load of the heat pump.

    Series or Parallel

    Sorry the Current rating of the inverter pv input is 18 amps. the panels max at 7.8A

    Series or Parallel

    Thanks for replying. It hasn't arrived yet, the pv power rating is 6kw, there is no mention of dual/ multi tracking MPPT, and looking at the terminals I think it is just one.

    Series or Parallel

    Morning, I am new to this site and starting my first PV project: to make my pool off grid with solar. I have got 10, 230 w panels with Vmpp of 26.6 and Voc of 37.4 ( apparently near 40v when hot). My hybrid 5 kw inverter max Voc of 500 and an input range of 120 - 450v. is there any advantages...
