@TaliaB sorry to keep asking but why do they have 3 parts, yet battery will have Negative & Positive terminals. Are we saying the 3rd part is for ground from the battery?

@TaliaB what size Keto Fuse disconnector would be suitable for a 5kw Sunsynk Inverter with a BSL Battery 51.2V 135AH 7kwH?

On the issue of remote hacking, I actually do worry about that & have always wondered how to have data being captured locally & only use Wi-Fi datalogger only for firmware updates.

Have you tried calling them out on this issue? I once had an installer shaft me & install electrical cables instead of DC cables & no MC-4 connectors on my first install. I had to rewire my panels & put correct breakers🤦🏼‍♂️

@PowerUser or anyone, at purchase, does the inverter ideally come with the latest/newest firmware or installer has to request this? Sorry for asking & not creating a separate thread.

@Scorp007 I’ve found that in some cases it’s scare mongering an end user to sell their existing batteries at rock bottom prices so the installer can they resell them to someone else either “as new/almost new” & maximise profits.

Yeah, I'll need to get a battery myself as well and then see how I can connect my Pv system and begin to get information, instead of all the time having to go to the inverter. Currently though am running a PIP2424MSX with a Blue Carbon 100ah battery. It's been good and reliable since 2014 and all my loads are on it except the stove. Also have a 200litre Solar Geyser so that helps reduce loads. Had hoped to get some Christmas bargains on batteries but no joy as yet. Just managed to get the 5kW Sunsynk for now. So I guess will have to wait till funds improve. Also running of 12 x 250w Solar Panels. Solar is beautiful, just not a cheap enterprise here in Africa where we don't have subsidies.

Mid 2014 MacBook Pro Retina... still going strong😃

@Onze Finca Wow, that's great to hear about your background on Graphical work as well as using Apple gear. Same here. Will definitely appreciate your insights once I've upgraded my system as I only have a Mac and most users here seem to be Windows minded. Look forward to it. Hopefully your journey in Pv will be a great one.

Then add elections money required also for next year's campaign materials... whatever loans they have to clear, in case they lose...

Physical disablement of mic yes, software based I'm able to always turn it on kikikiki

Sounds like a great way to get notifications to all in the house. Having been in IT myself, unfortunately I don't trust Google, Alexia or Siri knowing how they can be ever listening, but what can we do sometimes. May be an idea if you think of sharing your app or monetising it with others on this forum, am sure it will definitely be handy. That warning of loadshedding and the fact that inverter is a "set limit". I'm constantly tinkering with my system so I don't have an issue regularly monitoring it though your app sounds great. Does it work on on API for Macs?

I reckon the "loadshedding fellow" has gone on leave😁

@TaliaB now we are starting another rabbit hole discussion here. Do you or anyone know how Sunsynk quantifies it's daily cycle? Say we have loadshedding for 2hours in the morning and I discharge my battery down to say 80% (arbitrary number) and then recharge up to 100% and have another episode of loadshedding in the afternoon with similar draw, will that be considered 2-cycles or one? I thought a cycle was cumulative of say down to either cut-off or more than 50% and back up again so meaning over the course of two days depending on what is happening that may or could end up being 1-cycle.💁‍♂️ Yes, I also read, thoroughly the "700 times" bit in the warranty of Sunsynk and it's quite sad considering the levels of loadshedding we experience in Southern Africa. In Zimbabwe where I am it's absolutely can be as bad as having loadshedding beginning from 5:45am to 9pm daily, without a schedule nor notification either. I'm fortunate in that panels see me through out the day and battery from 5pm to 9pm, but if power doesn't come back am down the creek & over the waterfall. The other bit is we're in Africa for crying out loud, how often do we have or live at optimal temperature of 25ºC, it's normally between 12ºC-35º/40ºC, so already they have a wiggle-room to opt out of honouring the warranty and with loadshedding in SA at minimum twice a day... there's no hope.

Once thermal runaway begins it's only a matter of getting out of the way and foam or water will not really do much. Best would be to ensure you have an exit route out of your building or home that is uncluttered and has easy access, which also can be difficult as you have to be considerate of security to keep thieves out...

May the Karma Gods slap those weazels through the teeth. That's just not right for an installer or seller to take advantage of elderly people.😠😤

Early in my Solar journey would've loved to go blue, but yeah, that pricing was quite the huge shaft for me to enter into energy backup.

Solar and the renewable energy sector is ever evolving plus ever-changing and new regulations, which feels like the "mouth of a rabbit hole". We all are ever learning and unlearning, some things.

These fire suppression balls may help but if you have to employ them, chances are your installer didn't do a great job on your installation with correct breakers, surge protection devices on both the A/C and D/C side because truly if any issue starts from within the battery not much can be done once thermal runaway begins. But yes if the fire may be coming from somewhere else, gas cooker or something, they would come in handy to protect the fire from getting to the batteries. Just reflecting on how the BYD blade battery for vehicle EVs is touted as "very safe" even when punctured or the new Qili battery which is touted withstand extremely high and extremely low temperatures. Such if true would be exciting for the home market.

Maybe get him to join this powerforum, I feel a lot of people are looking for the easy, set and forget-it type of solution. It doesn't exist. Unfortunately also some unscrupulous installers promise the moon when they cannot even deliver anything leaving the dirt and then begin fear-mongering end-users even on the most minute issues such with threats of end-user losing their warranty, fire hazards etc.

Sunsynk is a great kit with many options and ways to tinker with it. It's also important for end-users to also temper their expectations of solar and be mindful that when days are overcast power generation also isn't so great and batteries are expensive.

That's a great piece of kit, but because of costs most installers don't seem to recommend them to end-users.

@TaliaByes pass through current.

Sorry @Scorp007 Let me paint my scenario and I pick your brain. Inverter is 5kW, surge for 5seconds to say 5,500w (these arbitrary numbers). Grid is available, but pass-through from grid to load is up to a maximum of say 8,000w for 10seconds. Just forget about SPD. If you one has a Voltage Regulator which can be set to 8,000w or just under which is the maximum of the inverter, then in theory there'll be no inverter overload, the appliances or equipment demanding that power would most likely cut out due to insufficient power and the inverter would not blow up. However, an inverter if it's pass-through maximum power is lower than what is going through it, the inverter will overload, likely blow or at best it may cut-off if the overload is tolerable, yes? So my thinking was about the architecture of having a voltage regulator that can limit grid out so the inverter is protected... food for thought? Now @Keill short answer is, yes an inverter can experience an overload, if the voltage passing through it exceeds it's rated maximum capacity because the demand is available from the grid but going through the inverter. Picture 5000litres of water from a Jojo tank having to pass through a straw. The garden or pool at the end may be able to accommodate the 5000litres, but going through the straw is the limitation hence the straw will burst.

So if one puts a correct SPD and Smart Voltage Regulator, which is set to limit voltage as per specific inverter, then this means, ideally there should not be an overload but the SPD or Voltage Regulator will not supply any power beyond what is being demanded by the loads then, which should result in the device demanding the load tripping or cutting off... yes?
