Great Video Keith! On the day of my inverter install the guys had this very issue... nuisance tripping on the Main House RCD. After a quick call to you, they wired it on its own 30mA RCD independent of the House RCD and its worked perfect ever since.

Excellent content, personally I only use RCBO’S with a switch neutral

[@hermanengelbrecht8513]

Hi Keith, it is SA law to have earth leakages, except lights. I had it on 2 jobs where its tripping on utility failure, so when loadshedding kicks in, it trips the el. Also our sans code required permanent earth N bond, so we hardwire it. Like usual very informative

[@sunsynk]

RCD should be used on everything I am referring to the inverter grid connection only

You should make a video about your installer approval system, who can apply and Who shouldn’t bother. After 35 attempts I received n email to say my documents were not in order, because I don’t have a website. I tried again and still waiting for a replay. I contacted your technical department yesterday and was told I must send an email. I wouldn’t even bother considering I no longer install Sunsynk products, however due to the fact that I have already installed a number of Sunsynk systems, wasted months of my time watching training videos because of your pathetic technical support in the past, I have to consider the customer warranty. Most customer have only requested Sunsynk due to the 10 year warranty, which is no longer be valid unless installed by an approved installer. what I would like to see is a video with you explains what is going to happen to all those people who you were happy to sell your product, DIYers, people like myself who cannot become an approved installer because I don’t have a website, yet I am a registered MIE with no restriction, registered with the DOL as an electrical contractor for the past 30 years, been installing backup systems since 2008 when load shedding started. By the way if you live in SA, I would suggest you read the SANS 10141 regs and take some this information shared in this video with a pinch of salt.This why sales people shouldn’t offer technical advice.

Thank you ja most houses have atrocious wiring! Meshing new with old is a real fun..

[@glenharris1401]

👏👏👏👏

[@williamhyman]

Thank-you ja earth rod same as IEC/SANS down here in RSA...

Good morning from my part of the world. I have a question that I'd like to address directly. I am currently attempting to connect an inverter in a batteryless state, with the specific intention of having solar power solely supply the load without any export to the grid. I have encountered difficulties configuring the settings for this purpose and am seeking guidance on the proper connection and any additional information that might be pertinent.

[@user-hp8hr8pu6z]

Keith are you looking at CATL's Sodium batteries, they say will be with us Q4 this year ?

[@andrevdberg1108]

Hi Keith i found especially on the 8kw inverter burnt relays/grid relay could you explain why would it burn/fuse together?

[@zjzozn]

Great show 👍🌈🥸

[@sidperry7748]

A wiring diagram would be very helpful 👍

[@SouthernRenewables]

Hi Keith If you were wiring x2 3.6kw inverters in parallel back to one RCBO/MCB, what would you advise on the rating of the device?

[@imatonkatoo]

Wish we had never had these Sunsynk installed . Installer has never shown us how to use it and I’m not an electrician in any shape or form. Effective home have never been any help to us. They took our money and ignore us. Batteries don’t seem to do anything still pulling loads of W from the grid and our bills have never gone down. Waste of £7500. Tried all the setting there is and nothing really changes. We’ve had it in our home that all the electric is off yet the grid still shows W going to the inverter. With the solar showing around 3000 W going to the inverter, battery full but soon empty when pumping over 3000 W to the inverter. I’ve tried load only battery only and I have no clue what’s the best setting? Also am I supposed to keep changing it from priority battery on a sunny day to load priority on a night time or a not so sunny day. Isn’t there a setttong where you can have it switch for you depending on weather

[@carlshaw7843]

Your older manuals did say you needed a RCD.

[@jorgedasilva3261]

Hi @williamhyman - not sure what you mean that no elcb is required for fixed installations. According to code all socket outlets(unless dedicated ones) and also geysers (as you said) need to be on Earth Leakage according to SANS10142-1

[@sunsynk]

I am referring to the inverter ac connection only not the essential loads

[@williamhyman]

Thank you awesome

[@williamhyman]

@herman no elcb required on fixed installation, unless Geyser ( new SANS 2021, before 2021 geyser not on elcb) and if you have a dedicated plug ( meaning freezer, fridge, aircon is the only appliance plugged in over 1 year) no need for elcb. this is elcb 30mA, 40A/63A..I personally don't connect elcb upstream & definitely no machine connected to elcb..inductive circuits are current sinks, they can cause nuisance tripping at 30mA...the Brits live in tents and wooden houses..different regulations..😂😂😂

[@gregbelcher937]

Good video but I found your constant swaying a real distraction. Did you record this on an ocean going cruise liner? 😉

[@WindyJAMiller]

You must be young, he has had a hip opperation, you will have the same fun one day.

[@Goreuncle]

You get distracted easily then

[@simonmoore4277]

I'm a little disappointed by this video, I thought you were going to describe the different types of RCDs, AC, A ,B, C etc. I hope that most sparks know (should know) about additional protection for cables buried in walls, socket outlets, etc. as part of their 7671 training... Btw, absolutely loving the "mini beast", made countless brews for "free" 😅

[@johnthomason8462]

Very useful, but please dont keep saying "its really simple" because it may be simple to you but not to us listeners, thats why we are listening. Good video otherwise, keep it up for us simpletons.

[@kevinpickett7249]

Basic stuff I tell people time and time again if clipped direct and in this case a fixed appliance it Dont need RCD protection 😂 just use common sense though 🤔 forgot its lacking in today's society

[@WindyJAMiller]

"never our equipment" - BS - you have firmware updates, to deal with problems!

[@alcaponemafia]

You need to show the wiring on a diagram to explain what you are talking about. Good info but bad display of what you are explaining due to no drawings or video footage of what you are explaining. DRAWINGS DRAWINGS DRAWINGS . YOU MUST MAKE IT SINPLE FOR US TO SEE WHAT YOU ARE EXPLAINING. You do this all the time . . you don't give drawings on any of your videos.

[@WindyJAMiller]

or worse, the manuals dont line up or have acurate information as its been carried over from another older version.
