I use the oven time for this - if no eskom the timer switches off and everyone know not to use the microwave after sunset. It works like a charm. Stove is gas Kettle i use the stove. I had to hide the electric kettle in the garage. No ironing at night Everything else runs as normal and it lasts me through out the night.

No regrets whatsoever. Turned out the developer put 16 tubes on a 200L geyser So i installed 150L geyser(3kw element) and connected it to the 16 tubes + 20 tubes for the 200L(2kw element)and connected them in series. Also added 2 X Geyserwise Max to control the pumps and they own batteries. It works like a charm. Water gets to 65 and 55 daily on average and i even have enough hot water to shower in the morning and all this without even using electricity. On good days i even get to 70 degrees. I have thought of getting a gas water heater for the rainy days but its not a priority at the moment.

Hi there, i don't know much about the inverter you have, but i know for a fact that Sunsynk inverter can handle the set up you want. Maybe look into changing your inverter. It has a CT coil that supply power to non essential devices( in my case, geyser, oven)

Looks like allot of thought went into this. Depending on your budget, i would target the reduction of your dependency on eskom first. As much as getting a battery and an invert would cater for load shedding, your consumption is still slightly high. Consider getting few panels, 6 - 8 when installing the inverter and the battery. That way you killing two birds with one stone( catering for load shedding and reducing the monthly cost). Also look into a smaller element for your geyser, belive me, it makes such a huge difference. I just changed mine from 4KW to 2 KW, now my solar production is enough to cater for geyzer and house consumption. 6KWH production maxing at 4KWH. Look into Hubble and Sunsynk, currently using sunsynk and loving it, unfortunately i cant comment on the Hubble but allot of guys have mostly good things to say about it. That should set you back R50K for inverter and battery, then panels 6 x 455W canadian solar should be around R15K then installation and accessories. I built my system over phases, within four months and i feel i wasted money by going the gell batteries and growatt inverter.

The 6KWh is my solar production capacity. The Geyzer has a 4kw element that i will change to a 2KW.

Could the problem then be defects on the cubes? Also, i was thinking of taking the tubes out as i don't have enough space for the another set.

Its the same tubes you have. 12 of them and they facing North.

Morning all. Please help with my water heating requirements. I would to rely less on Eskom, so i need a optimal water heating system for the house. I currently have 6kw solar array installed and have solar tube that i think are useless as they hardly ever go past 50 degrees in summer let alone in winter. I have recently installed 2 X 49KG gas for the newly converted gas stove. Needs Which options below will cover most of my needs? Stay off Eskom Have enough hot water on sunny days. Have hot water during cloudy and rainy days. Current situation 150L Geyzer Gewiz timer Solar tube Servicing 2 adults and 2 kids - and guests some time 4KW element Connected to solar via coil on Sunsynk Option 1 Current geyzer servicing the master bedroom. Another 200L or 300L servicing the rest of the house relying mostly on solar Remove the solar tube to make way for extra 2 panels to boost production Gas heating system for rainy day. This will barely be used because of the solar production will heat the water during the day. Option 2 No additional geyzer. Gas heating system for the whole house. For cloudy days and normal sunny days. and when i have guests over. and morning showers. Nic over and out.

Where might i get a bi-directional prepaid meter for use in Pretoria, Centurion? At this stage i am willing to buy one myself, provided it can work in my house.

Have you looked into power optimizers for the two panels? I saw a few a while back for like a grand each.

Nope. Try it and monitor the consumption. Everything in my house is on the essential load on my inverter. Maybe your inverter might work different to my sunsynk with regards to blending power.

Just my 2c, growatts are terrible when it comes to blending power. I changed my growatt to a sunsync and have never looked back.

I would consider adding at least 8 if you have space. 5 panels might give you less productions during overcast, not enough volts.

I can contribute to the geyser timers. I would suggest you get another geyser. Make sure they both have 2kw element. as for the schedule, instead of 16:00, switch them on during the day when you have solar. I switch mine from 10:00 to 15:00 @65 degrees. After that, i charge my battery as i use it to offset where production is not enough to power the element. With the family of 4 with 2 little ones, i plan on installing another geyser to provide hot water to the master bedroom. The existing one will serve the rest of the house with the kids and guests bathroom and the kitchen. My thinking is that, under normal circumstances, we all can use water from the master and in the morning we can shower in the other bathrooms. That way i wont have to switch on the geysers in the morning, Only during the day when there is sun.
