Thanks @Speedster and @GreenFields. Lots of unused power when you look at whole day. We are only using about 1/4 of potential. But the power is not enough for peak times when we want to cook, charge battery, do geyser and run pumps. That's normaly around mid day. Already have geysers on timers and they are all new.

Hi all, We are completely Offgrid and I have successfully upgraded our setup to the following: - 48V / 5kva Victron Multiplus * 2 -- Giving about 8000W - 6600W of solar - Our controller can pull a max of 5800W from panels - Lead Acid batteries at 220Ah The biggest power draw item we have are the 150L * 2 water geysers and some pumps that go up to 2300W and only run during the day. We also would like to cook using electric during the day and eventually at night as well. Questions -- Is it realistic to cook entirely using our inverter/solar setup as long as we have enough solar or batteries of course? I estimate we won't go over 5000w being used on stove at any time. Any detrimental effects on inverter? the seller and installer were both advising me against pushing the two inverters that hard so now I am unsure. If you were in my shoes, what would you upgrade next and under R60, 000 - Would you upgrade the solar to 10,000w -- This will cost me about R40, 000 - Crucially - Would you get a bigger solar wattage, i.e 10, 000w total so that geyser elements (4000w total can run comfortably during the day) or would you buy a heat pump...or just save for batteries. - Would you upgrade the batteries? This amount will only get us about 10, 000kwh or so of hubble/pylon. - Have people here experimented with the Lithium Phosphate cells and is that some thing viable here in Africa i.e purchasing cells and making own batteries. All advice welcome!

Thanks for all the updates. Extremely useful.

If you don't mind me asking, how did you get the cells?

Hi Ian, Where did you get your lifepo cells?

Hi all, I have a 5kw 24v Victron Multiplus which is currently limited to pulling only 3000w from my 5500w panels. I would like to install 2 geysers with each having 2000w elements. My question is, what is the best way of powering 1 geyser ONLY after the other is fully heated. For context, I would like to use a relay off the charge controller or gx device. Also some advice on wiring this would be nice. Also kindly suggest some decent relays that I can use for this purpose. Regards

Thanks all, tracking all the advice.

Hi all, Planning on purchasing an 8k sunsynk, 2 Hubble 5.5 and an ITS Heatpump. My question is, would it be wise to house all these in the same room (2m * 1.5m big). My assumption is that the heat from the sunsynk will help improve the efficiency of the heat pump. Is that realistic and should I expect any issues? Second question, this outhouse that will host the power equipment and the heat pump is about 8m away from where I would want to place a single big geyser/storage tank for the whole house. Is this a wise thing to do and is it possible for us to run hot water pipes through the ground from the outhouse holding the heat pump to the geyser/storage tank? Thank you.
