When you go to Inverter on and you're hooked up to shore power it uses the built-in transfer switch to pass the AC shore power through to your connected outlets, bypassing the inverter part altogether. Excess amperage is used to charge the batteries. That is unless you have the Power Assist turned on. That's a Victron answer . Sounds very much like a bypass and Power Assist sounds very much like peak shaving.

So at what point does it stop inverting for a start, have you done a test have you seen a maximum discharge and then the grid actually supplementing till 12kw. Please share or does it just switch over.

Could use a Victron in line fuse

The problem is the fuse disconnectors are rated 160amp as well and the next size up requires a higher rated holder to accommodate the higher rated fuses but I will figure something out. I feel that Sunsynk have an obligation to provide a quick video that is clear on this because when I look at this forum there seems to be confusion. I could be wrong but people need clarity me included

The batteries here are capable of an 800amp continuous discharge but the fuses are rated 160 for each battery and the fupacts don't go over that so will be a challenge not to blow fuses

Ok so you have set your 8800 invertor at 8000 which is default. now take your max discharge current on the Sunsynk 8.8 spec sheet is 185 and I know this because I can not set mine to more then that. At nominal voltage mine being 52v this equates to 9620 Watts .In your example you still within spec. When you go over that it will simply switch over to grid and this is now passthrough. Again that's why I need to see it I will do the test myself with ae purely resoative loads and then report.I have a master slave setup so I need to hit over 20kw

Now it's a typo,why has that not been announced on a bull horn no wonder the relays have welded contacts and breaking down. Now why would you want to use this passthrough function then hit load shedding and boom Ac trip. Again this nonsense about passthrough has got people thinking they can now overload the essential output.If grid goes down then you are restricted to inverting capacity. The example you show above would be equal to at ac voltage 41 amps and the only example I have seen on the forum. I would like to see a video cranking it up to 12kw and just staying there and if it is indeed supplmenting with grid on a maxed out invertor I'll eat my hat.please know that I understand it will blend within capacity but I'm very doubtful on the passthrough as described in this community.Many people including installers are giving different opinions.Pregnant or not pregnant simple.Where is an approved Sunsynk installer to set the record straight

I want any Sunsynk guy to show me 4 elements 3kw each on a 8.8kw invertor and some pictures of flow chart and a clamp meter on the grid input. Sorry let's make that 6 elements so we can test the 90amp blending theory

Exactly what is Dc to Ac ?it means it's inverting and is limited to 8.8kw and some period of peak. Ac to Ac is passthrough so I don't understand .It doesn't mean supplement or blend grid with a maxed out inverting invertor or like you say DC to Ac.Litrature states passthrough not supplementing or blending.Passthrough of an alternative Ac supply

No ,this is not true. When you program your minimums say 80% that means battery wont be used lower than 80% and the grid will then feed those loads on the essential side without any inverting ie passthrough. Don't overload your essential side of the invertor it will handle peaks which i suspect you guys are experiencing ,but not for long periods and will trip.If you are looking to supplement the grid then look at peak shaving settings but again 8kw is 8kw klaa. Just installed 2x8kw maxed out with 2xFreedom Won 15/12 and have hit it with everything incuding the kitchen sink and it will ac overload when it is inverting and you are above spec
