    I personally don't like it when a manufacturer, supplier or distributor comes onto these forums and post to tell us how great they or their product is and how much they care (biggest lie ever). If they post something like the above then they must be willing to respond to questions being asked on the specific post. They treat it as their own personal advertising board without taking the responsibility. I believe if they post here then the admins of these forums must enforce responsibility rules and remove their "advertisement" posts if they don't respond.
    I am in the process of upgrading my system to a bigger inverter and battery and I am in the research phase. I remember how Sunsynk ( @Keith Gough @David Drake ) treated their customers and that will affect my decision. I am watching the other guys as well.
    I see some activity from Solis on the forums lately so why haven't you responded on this post yet, @Solis Inverters SA ?

    He good news is @TaliaB has been discharge and he is busy recharging hopefully to 100% SOC on a family farm.
    His oxygen levels still need to recover and could take a while.
    Thanks for the support on behalf of our friend.

    TheMac reacted to reapster in Proportional SSR Geyser Control   
    Went down this road recently. Worth keeping in mind that most SSRs sold locally are fakes, specifically fotek fakes. See: https://protosupplies.com/inferior-counterfeit-fotek-ssr-25-solid-state-relays-on-the-market/
    I recently purchased from a local supplier (I don't blame them, I expect they weren't aware - I'm just trying to point out that we are likely not buying real/properly rated SSRs here), and it was sold as a "SSR-60 DA", implying 60A rated switching current. After realising this is likely not a real fotek (no datasheet available for this alleged model from fotek, which is a reputable brand), turns out its got a 40A BTA41 1000B triac inside, which in all fairness is way better than what I expected given that its absolutely not a legitimate fotek SSR. Just know what you're getting. Given these tend to fail closed, I'd never trust a locally sourced SSR after this.

    I had a look at the 5A and it is good for my budget.

    Thank you for the advice.

    I own three Victron Blue Smart 12V 25A chargers, and I can honestly say they’re the best chargers I’ve ever used. They handle everything from small 12V 8Ah lead-acid batteries up to 150Ah without any risk of overcharging. The chargers automatically adjust based on the battery’s internal resistance, so the charging process is always safe and accurate.
    I mainly use two of them to maintain my Willard 12V 120Ah (734CCA) truck battery, and they’ve been flawless. The separate charging profiles for LiFePO4 and lead-acid work exactly as expected. My oldest unit is now six years old and still performs like new.
    I’ve also never had a single issue with the Bluetooth app connection is stable, settings are easy to adjust, and the monitoring is excellent. The built-in reverse polarity and short-circuit protection actually work as advertised, without causing any damage to the charger.
    As @Scorp007 mentioned, it’s a very handy charger, and you really don’t need any external test equipment the charger gives you all the data you need.
    A few screenshots of the Bluetooth app below.

    Yes I have used the smart units on a MPPT and the APP is basically the same. You get the graphs, capacity, can change any setting all via the APP via Bluetooth. It's really so good not having to hook up multimeters to get the readings.
    This is is the go to method used by most mobile installs of PV and charging Lithiums. I have never heard of anyone having a problem around the remote functions. Costly but worth it.
    Great to have one APP and talk to most Victron gadgets.

    Yes the Victron is a good charger and the smart comes with handy Bluetooth to see all the stats remotely.

    Long ago there was an advert for either Band-Aid or Elastoplast with a kid removing his plaster and asking "Where my cut go?". I suspect they will be asking "Where my electricity go?"

    Failure rate could also include all those that have problems due to wrong settings. We just have to see how many questions are asked where CT that is well spelled out is connected the wrong way round. Documentation is sometimes to be blamed.

    Indeed. And the way you use it conforms nicely to my earlier point.... You already know what to look for and you are able to pick up on any errors or false statements of the AI. You use it to save you some time but not to solve your issues or ignorance for you. I bet you always go over what the AI gave you just to make sure its correct.

    I use Ai extensively (mostly Grok as it's great with coding) to speed up mobile app development, massive time-saver.
    There are good and bad use cases for Ai, you see all the dodgy folk (Politicians included) that think Ai will make them "clever" they are sooooo wrong 🤣 coz they don't realise you need at least a few decent braincells to use Ai correctly and effectively.

    Anyways.... AI generated content seems obviously to be out-of-place amongst normal conversation so I think everyone will already know you used it. As long as you add a little genuine Welkom charm in there as well. 😄

    I am part of a programmer online discussion forum and this trend has been discussed at length on there. It basically comes down to this; The people who can afford to use AI usually don't and those that cannot afford to, do.
    The uninformed are usually quick to run to AI, unaware that there are many false statements coming from it. They will never learn the real facts.
    I have been in the computer world far too long to fall for this fad. I treasure experience and great insight coming from an "ou ballie" more. 😄 Fortunately there are many greatly experienced guys on this forum that have already proven their chops. They are well known by us that frequent this forum.
    I hope such user accounts get removed.

    Wow, your load is exceptionally low.
    I had a Growatt 5kW inverter, and their settings are very sensitive if the firmware is not up to date – get the person who installed the system for you to update it.
