January 8, 20224 yr Hi all, With my solar install I decided to get the Geyserwise PV system as well for the hooot water needs. Colleague at work had it and was very happy with his 6 person family on a 200L system. We are only two and 150L. Got the system without the solar panels from LiveSystainable on special for just under 9k delivered. I had 9 x 540w Ja panels and 1 x 535w. 8 panels on the inverter string and 1 x 535 plus 1x 540 on the geyserwise. Damnnn guys, I have not had the geyser on AC since 24 December and we had rain up to the 28th. Even with miserable weather it got up to 60+ degrees. Drops down to about 50 during the night on bad days and 60ish on good days but we are used to 50 degrees ond the old AC system where it ran 3 hours total a day. 1.5 Early morning and 1.5 afternoon before peak times. I know some guys use other systems from their normal PV systems and inverters but this is just so amazing. It's a saving of R900 a month. For most it's easy to install but for me it was a tad difficult due to where my geyser is located. Had to extend thermo cables and run around 6 meters of 2.5mm AC cabling + 6mm DC cabling. Fully recommended. It pays itself back in 16 months. Will still see what winter brings but since my roof is 2 stories high with no trees we get loads of sunshine.
August 7, 20223 yr HI there, Im looking at doing this type of installation too. I currently have a PV system installed with 15 x 330w panels and a 5Kva inverter. Is it possible to use my current panels to feed into the geyserwise MPPT? I dont have much space for more panels and seeing as i only use Max 2Kw i thought this would be best for me too. Any comments/ suggestions would be highly appreciated?
August 11, 20223 yr Hi Joe, some help needed...I have 3 x 350w pannels with the above pv150vdc but I cannot seem to get to 72w for this water heater...you got any ideas what combination to try...considering no pannels on stock? Thanks Andrew

Thanks Andrew As far as I have seen 4 panels are too much for the 900W element. 3 x 350W seems just a bit higher than the 3 x 330W recommended but I think the Voc can be 150V not 72V.
