You could find these brand new for R10,990 right now. You might want to revisit the price.

Have you tried PowerforumStore? https://powerforum-store.co.za/collections/batteries/products/hubble-lithium-am-5-5-12kwh-51-2v-battery Speak to Wimpie, he mentioned a while ago he could get pretty good prices. Regards, Heine

You're welcome

Hi Neil, I think it makes perfect sense. Irun solar-assistant (https://solar-assistant.io/help/getting-started/prepare-device) which I see appears to support Sunsynk inverters too. Solar-assistant makes it very easy to configure rules such as, switch to Eskom when battery power drops below X. I ran my Geyserwise PTC element (https://livestainable.co.za/products/geyserwise-2kw-230v-stainless-steel-ptc-geyser-element-2000w-ac-only?variant=43669700608180&country=ZA&currency=ZAR&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&gad_source=1&gclid=Cj0KCQjwna6_BhCbARIsALId2Z0gT62T5gpLeDw2t85-oQNwNH8OdKndp23Q4OnxU5nqsG88UlFSr4caAm-iEALw_wcB) from a single 5kw Kodak when the tubes did not generate enough power until not too ago using Solar-assistant and also some additional home automation (Homeassistant) to manage total load. I now have 2 x Kodak 5kw and more panels so life is less complicated as far as managing the load. I was actually able to pay for much of the expansion using my calculated saving from my initial system over a couple of years. I also decided to go with a AC powered pump for the tubes and that is connected to my inverter too. Why another battery and tiny solar panel I reasoned. You don't mention which area you reside in. Here in Cape Town and surrounds we really struggle a bit with solar generation during winter. You might not have those issues to also consider. In all honesty, if I had the opportunity to do it all other gain, the one thing I would change would be rather go for a heat pump instead of the tubes. In summer, I often have to cool down the water overnight using the Geyserwise "away mode", but in winter it is a challenge and often have to boost the temperature using the element, Having said that, if you have a regular 3kw or high element for your geyser, I would suggest be very careful with your current 5kw setup. Downgrading the wattage and/or going for a Geyserwise PTC element might be something to consider. What I also did when I only had a single 5kw inverter was install a change over switch for the geyser which allowed me to switch to Eskom directly in winter and via the inverter in summer and then still had Solar-assistant to manage the actual source of power during summer. Hope it helped and I didn't confuse the heck out of you. If there is anything unclear or you more question please reach out. Kind regards, Heine

Good day, haudevbe. Thank you for a very comprehensive reply and some very good suggestions. I really appreciate it. As you mentioned, I am hoping that someone has already managed to make this combination work whom could share some insights. Kind regards, Heine

Good day, I would love to know whether anyone has a working system with something like the "Solis S6 Pro 6kW Advanced Hybrid" inverters and "Revov R100" batteries. Reason for asking is that I would like upgrade my inverters without necessarily replacing my batteries. Kind regards, Heine

Hi Marius, Been a while, but did you sell all of those or do you have some left?

I bought one in March last year and have been happy enough to purchase a second a few months ago for a very good price from GWStore. I am considering getting a third some time in the (hopefully not too distant) future.

Yes it is

Bump R1600

I know this is a pretty old thread, but I was happy enough with my R100 that after 15 months of use, I bought a second unit.

Well, as it turns out this Kodak which was apparently "working until the day I upgraded" was sold to me by one of the member of this forum and it's busted! Was running okay during the day and as soon as my wife switched on one induction plate, which usually pushes the load to about 1.4k for short spells as it turns on and off the inverter tripped. Well, at least I know the charge controller works. I have tested that before. Hopefully when I add more panels to it as I plan to, it does not trip too and it can just help charge the batteries. Regards, Heine

I am wondering whether any else noticed something similar or my have an explanation. I recently bought a used OG 5.48 to use in parallel to my existing inverter. I ran out of space where my existing installation is (was) and started a "new" installation alone the long side of the garage. First step after plastering nicely and painting was to mount the unused inverter, trunking etc., etc. Today I had an electrician remove AC in and out from my original inverter and connect the new (used) inverter and much to my surprise, the consumption in the house and the rate of discharge from the battery nearly tripled! Attached graphs for the past 3 hours or so and another for yesterday and a before and after for the day

Hi Nick, I have a similar setup although I decided on evacuated tube collector and just had my electrician connect the geyser to a change over switch with which I can manually (does not happen often) switch between Eskom and my inverter. Sometimes I just switch on the element for a while to boost the water temperature like I did today. I still want to try and automate that, but I would typically only do it when the battery has reasonable charge and there is some sun. When it is really overcast, I switch the geyser to Eskom, switch the element on an just let it heat up without drawing from the inverter. Regards, Heine

Ouch, bad news indeed.

Hi Not From Eskom, I assume you have disconnected for a few minutes and connected again?

Short update... I sourced 2 x 545W panels which should be on their way shortly and just purchased an EPEVER 30A MPPT as per @Scorp007's suggestion. I will feedback some more once it installed.

Thank you everybody for the input. I learned quite a bit. I really liked the EPEVER suggestion @Scorp007 made. I think however I will start with adding a few more panels on the east side as @GreenFields suggested and wonder whether anybody has tried mixing and matching different brands. As I mentioned, I have four Canadian Solar 455's and Seraphim 460W panels may be a close match I thought. Any thoughts?

Thank you GreenFields, just adding panels on the east side is also something I have considered, it is just that the 455's are now discontinued so part of the thinking was to add 605W x 2 on the other side.

There is a Shoto specific cable available on the Solar-assistant shop. I also found the values coming from inverter to be unreliable with a totally different setup. Purchasing the correct cable to connect battery to Raspberry Pi solves that issue
