- Hi, in this video, I want to investigate my two dead SUN GTIL inverters. Can there be a successful repair attempt, or is all lost?

I own two 1KW versions of that, and they have been operational for over three years, still functioning perfectly. This is, of course, with the inclusion of all the necessary protective devices.
Bummer too bad, now I will have to keep an eye on my two.
But it's great that your units are still holding up well. You are having them indoors in a temperate environment. Think you are much better of than me...
Probably need a heavy duty one. Growatt 6kW Grid-Tie Inverter | MIN 6000TL-X
Look at the deye hybrid series..
They are the prodigy's to the sun inverters
Deye Hybrid is coming soon for the new system :)
@@RolandW_DIYEnergyandMore have the Sunsynk versions running now for a year..
These are amazing, and you find the menu and terms very familiar ;)
I am going to use a Pow Mr 4,5kW hybrid inverter with a 24V 560Ah Lifepo4 battery. Now I am not shure anymore, if I should connect the AC input, even i have a 275V SPD right next to it installed and a over/undervoltage protector relay is at the main input of our house. It seems this Inverter have no relay for "bypass"-mode. The manual tells 94% efficiency in "Line Mode". It has a build in battery for wake up, so no AC-Input seems to be needed and when I let the ATS make the bypass I have 100% efficiency but the ATS with magnetic coils inside house is quite noisy. I am still undecided. How reliable the Inverter is...I dont know, yet, but he was not too expensive, feels worthy and looks good : )
For Off-grid systems it is very important to use SPDs at the AC-Output as well, as you are operating in a closed system where induced voltage surges can not easily get out of the inverter. But of course lets all hope never get such occurrences at all.
@@RolandW_DIYEnergyandMore Before I was reading your response I asked my self, if it is really good to make the earth bonding to define a Neutral at the Inverter output to make RCB's work, cause if any surge occours it will destroy your inverter on the way to ground. If no ground is offered the surge will search some other way, not through the inverter and wouldn't destroy him. I heard some inverters dont like grouning (exept on housing). So I am still very undecided about the grounding. The SPD,s on output also offers a path for a power surge, so I am also not sure if it is advantageous to offer a path through the Inverter and SPD. I am adding some varistors (20D391K) on input and output between L and N against inductive backfire and other power surges. My solar panels also have no SPD's. They are mounted on a well grounded tin roof (right beside the house on much lower level as the roof of the house) with welded frame which I grounded with a ground rod. So my phisolsophy is to keep Everything insulated to force any surge not to use the way through my system. Is anything wrong about that?
@@topeye4202 SPDs do provide defined shotcuts to ground outside of electronic appliances. That is exactly what we want. If there is no grounding provided, the surge will find a random path to ground. That will always be inside electronic devices as their PCBs are the weakpoints inside our electrical installations. It doesn't need to be the inverter where that happens. I had a case where all my appliances where shot in my at that time ungrounded/unbonded off-grid system. Just the inverter survived without any damage...
@@RolandW_DIYEnergyandMore Thats bad, where did this surge came from? So i will add SPD's at output too, but about the grounding i am still undecided cause some one told the inverters dont like grounding, he was from USA...is this only with transformerless inverters ?
@@topeye4202 US has different equipment as they have a split phase. many people even use European inverters. Such configurations are vert tricky and one needs to know what he is doing.
My off-grid system surge damage as well came from a nearby lightning. It ruined the whole pool equipment. was quite a big, expensive damage...
