https://www.sunsynk.org/approvedinstallers Search that for 'master' and see which of them are in Cape Town. Are a few. Deye and sunsynk are almost the same, so they'll be able to help you out. My suggestion is to get a professional involved ASAP, they'll sort it out hopefully in a few hours.

Durban Shipping to city centres works out to around R1000 150kg!

Correction, this is from feb 2021

Will include the remote monitoring device (as pictured on top of the unit) for free

Sold

MLT Powerstar G2 18kva single phase inverter Age : Purchased around 2014/15 Rock solid inverter, MLT quality Still in good condition. Not moved around. Shipping : prefer not @ 150kg but we could get quotes if needed Price : 30k Unit is currently in operation and will be a week before we can confirm anything, currently awaiting quotes on a new system. legacy_powerstar_specifications.pdf

Is the 12Kw sunsynk also affected by this issue?

How's magneto in this regard? Same as deye exactly?

Get @Steve87to check your configuration out, sounds like the settings need to be checked. Kodak should work fine off grid

Support for most important setting of Must and SRNE inverters. https://solar-assistant.io/help/updates/changelog Best to contact them

I also have sensitive hearing.. Lucky then that I ended up with a voltronic inverter, prior to finding out from these forums that sunsynk is better

Use solar assistant... Remotely can change the settings for a temporary time period, after which it will revert to normal. Perfect for preparing for load shedding.

Give @Steve87 a shout!

Had this occurring every so often. Restarting inverter solves it. Eventually got a rs232 to usb cable which sorted it for good. The micro USB connection is iffy at times and for long term data monitoring.

Thanks @Steve87 for helping us rectify a dodgy uncompliant solar installation with many mistakes on the AC and DC side. It's been a mission to discover and then sort all the issues out, but @Steve87has been super helpful in rectifying the situation, working through the weekend to get the system compliant. Honest, helpful great guy who knows his stuff. Wishing you well in the future!

https://solar-assistant.io/shop/products/shoto I would just buy this

So is that the only difference, feeding back into the grid vs not? So a grid tied inverter with a battery, with export / feedback disabled, will have the same functionality as the hybrid off grid? I read elsewhere that a grid tied inverter, during load shedding, the solar does not charge the batteries? In the case of a tesla powerwall which incorporates a inverter, coupled with grid tied inverters for solar, will this still apply, or will solar be able to charge due to the single inverter within the powerwall?

Hi Both seem to achieve the same outcome, solar + battery + grid can carry loads during the day / night. 1. Hybrid off grid + battery. 2. Grid tied inverter + battery. With regards to what is happening behind the scene, can someone clarify the difference in functionality?

I suggest you get some professional electricians to check your cabling as well... We had 2 inverters motherboards get fried for seemingly no reason, ended up being a cut cable, when wet it would spike suddenly. Wasn't malfunctioning under normal circumstances even. Our normal electrician didn't have the equipment nor know how to diagnose. Called in another electrician, they used something called "thumping" to locate a cut cable outside underground.
