Hi guys, Has anyone uninstalled a GoSolr system at the end of the 3yr contract. What was your experience with the uninstall ? Has anyone outright purchased their rental system from GoSolr? Did the pricing make sense ?

Yes, I almost always dip into my fully charged batteries with the midday geyser run and the morning geyser run completely obliterates the batteries down to about 25% or so

Thank you very much for sharing your wealth of knowledge here folks. Highly, highly appreciate this. Definitely saved me some money that I was ready to spend on an ITS unit. I guess I'm dealing with a similar problem that most of you encounter - Striking the balance between trying to save money, have reliable supply of electricity and maintain peace in the household. Seeing that I've been running on a rental system (GoSolr) who's contract comes to an end in a few months time and with prices certainly being a lot more friendlier than they were when I rented the GoSolr system 3 years back, I will hold out for now and rather focus on Investing on my own system that will give me enough headroom to run through Winter with enough power to spare.

Hi guys, I need some guidance on how to maintain peace with the Minister of Hot Water in the household in winter. Current Setup; 200l above roof solar geyser with tubes and 4kw element controlled via geyserwise Basic Go-Solr system with 5kw inverter, 10kwh battery and 3.6kw solar plant In Summer, Battery bank is usually full by around 11am and geyserwise kicks in and takes water to max of 75 degrees. Enough for 2 evening showers. Geyser runs for about 30mins At around 4am to take water to about 55c but then it’s eating to batteries but it’s minimal. All in all, I’m able to run household with very little to no need for Eskom on most days. in Winter, the system struggles and realises heavily on Eskom and sometimes the water just isn’t hot enough, leading to much gnashing of teeth from you know who. What’s the best bang for buck way to lower dependence on Eskom and have reliable supply of hot water in winter ? Adding a heat pump ? How should that be integrated into the existing system for it to be optimal ? And what size heat pump? Adding a second geyser ? How should that be connected ? Doing both ? Other creative methods ?

Hi guys, I have a 5kw Deye inverter (lease from Gosolr) that is behaving very strangely. The system date and time on the Inverter keeps defaulting to a random date and time. For example, I set the correct date and time 2 days ago but it says today is now the 2nd of July 17h13. This is very frustrating because this means my time of use settings are pointless and because I’m now on Time of use billing, I can’t effectively control my electricity bill. How can I fix this ?

Thanks for the input, I found the problem. The system date and time on the inverter was wrong, for some reason it was reading as 9th August 2023 21h47. Don’t know how long it’s been off sync but probably explain why my electricity bill for the last few months made no sense. Have synced it and immediately started pulling from battery and will monitor to see if it doesn’t default back

Hi all, with new flexi tariffs coming into play I’ve set up my system (5kw inverter plus 10kwh battery bank) to be on 40% SOC by 5am and then set the battery limit to be on 30%. It’s 05h30 my battery is on 40% but the system is using grid power instead of battery. Should the system not be prioritising battery use based on these settings- What am I doing wrong ?

Thanks for the feedback folks, Seems I'll have to lower the shower head abit

Hey folks, I have a 200L solar geyser that is controlled by a geyserwise unit. I also boost this geyser with PV during the day to get it to 65c and through grid power in the mornings. I have a strange phenomenon which I'm hoping you can help with. In the main bedroom I have a big shower with a 50 sq cm ceiling mounted rain shower head which also has a built in hand shower. In winter, even with the geyserwise showing water temp at 65 - 70c, the water coming out of the big shower head feels Luke warm at best but this problem doesn't seem to be an issue in the smaller showers with regular sized shower heads. The water temperature from the hand shower attached to the big shower head also feels several degrees warmer than the big shower head. is there something inherent to larger shower heads that may be causing this ? Does water loose that much temp as it falls from the shower head (which is about 1 m above my head) ? in summer this doesn't seem to be a problem although there would still be a notable difference in water temp between the Shower head and attached hand shower.

I find that the 5kw is actually plenty sufficient for my needs, I don’t think I’ve ever come anywhere close to the 7kw max passthrough capacity . I do however wish I had added 4 more panels to get batteries full quicker and also help out on those cloudy days. Since I’ve got a solar geyser, even with load shedding, the PV collector still heats up the water so I’ll still have decent 50C water (in winter) for the evening showers. I now fire it up to 70C purely on batteries and PV, this now leaves me with enough hot water for the 2 evening showers and 2 morning showers without having to fire up the geyser again in the morning. Will see how effective this will be as we head deeper into winter. I’m not happy with over night temp loses on the geyser (over 15C on some nights). I now average about 2kwh a day, and most of this is from the geyser run at midday (once 85% SOC is reached on the batteries - Eskom jumps is a little bit, I could possibly drop SOC setting to 75%, but I would likely not go into the night with full batteries if I did this or I’d have to sacrifice pool pump time). I imagine that in the summer months, I won’t need Eskom at all on most days, except rainy days. On average with this setup, by 16h30, I’ve got my 2 batteries at 100%, a 200L geyser with > 70C water, a clean pool and often with a dishwasher / laundry load done. My house then runs fully on batteries over night. Once I get a heat pump in the mix (a 3.6kw ITS heat pump pulls about 800w), I’ll have plenty of capacity to run without so much sequencing and monitoring and will move the geyser to essential. for now, I’m looking to get into Home Assistant to use some “intelligence” to run automation on the geyser and pool pump taking into account PV, weather forecasts, SOC and that sort of thing. For my current needs, If I had R45k to spend, and had to choose between a 5kw and 8kw, I’d take the 5kw and fund a heat pump with the difference, should headroom become a concern later, I’d then add another 5kw which also gives some redundancy should an inverter fall apart. sorry for essay 😂

No, it’s a kwikot 4kw element

The temp setting is set at 65 degrees

The 3 flames on the geyserwise turn from solid and start blinking and the geyser temperature just holds temp at 55 degrees. when I look at the current draw on the inverter, it’s gone back to base load so means geyser element is off

Hi guys, I have a problem with my system using battery when solar production dips, this happens even though my battery % is below my set % on time of use settings. any insights as to why this is happening ? This problem only started today - everything was working well, i made no changes to the system at all but i did have an earth leakage trip on the lights circuit, not sure if this is related

Hi folks, I have recently had a solar system installed and have my solar geyser which is controlled by a geyserwise connected on the non essential side. I have set my geyser element to come on at midday and have set the temp to 65 degrees (maximum allowable on geyserwise), however it only heats up to 55 degrees and then the element switches off. Any ideas on why this would be happening ?

in the morning, I discharge to 35% SOC to heat up the geyser, then let the batteries charge up to 100% during the rest of the morning in the afternoon I discharge again but this time to 85% SOC to boost the geyser for the evening showers. The battery then charged up to 100% again in preparation for running the house through the night

So because I only drain my batteries to 35% does it mean that I’m not cycling the batteries at all? Is this a good or a bad thing ?

Hi all, I’ve been lurking around these forums for quite a while now and finally got my installation done earlier this week. - Deye 5kw Inverter - 2 x 5kwh Freedomwon E-Tower - 8 x 460w panels (3.68kw) all circuits on essential except geyser. Before this installation, the 2 person household used an average 17kwh per day. We have a gas stove, solar geyser and a 1.1kw pool pump and led lights throughout the house. After installation and with careful sequencing of activities and sheer power dictatorship we have managed to keep Eskom use below 3kwh per day. The daily routine is as follows. Battery is usually 50%/60% SOC by 5am, I then fire up the geyser for an hour (4kw element 😭) via the geyserwise controller to heat up water for the 2 morning showers, I have set the battery minimum SOC to 35%. The battery does the heavy lifting and Eskom contributes about 1 - 1.5kwh. This usually takes the water from 30 degrees to about 48 degrees. Between sunrise and 12h00 the following takes place - pool pump runs for 1 hr - batteries charge up to 100% soc - occasionally 1 load of laundry gets done Between 12h00 and Sunset, the following takes place: - Boost the solar geyser for an hour (12h30 - 13h30), battery drain set to 85% SOC. On a good day Solar and battery do most of the work but Eskom occasionally contribute 1kwh in the last 15mins - Charge batteries up to 100% again - Run pool pump for another hour from 14h00 - 15h00, purely off solar (battery SOC min of 100% set from 14h00 to 17h00) Question is Does my power management routine and these geyser runs harm my batteries in anyway ? Does the midday geyser run off the batteries count as a cycle ? Side note: I’m looking into a heat pump to ease the power draw and will consider a smaller element in the meantime. Also heading into the first cloudy weekend so will need to make sacrifices here
