Small solar advice (5KVA hybrid system)

24kW, this gent isn't playing🤣.

@wingnut771 I spoke to my younger brother. Said I will only install this if he thinks my current setup would be a bit too inconvenient for him, since he will be moving in around June. Basically, he is potentially going to pay for it. I just have to get measurements tonight, and I will be ordering one this week. Going for the 5kW.

Actually will make a big difference. My AC capacity will increase to 8.6kW, and battery capacity will increase to 17kWh with my existing GEL bank.

I like that but sadly the installation seems too complicated for me but perfect for those experienced with solar.

Can’t imagine the installers are too keen on it either as they don’t get to add their margins when they don’t supply the equipment too

In your case would avoid personally. I don't think you can expand the battery capacity on this thing. I am only going for it as I already have a system running, and this would only supply the kitchen.

I average 2kWh a day consumption on the kitchen. The 5kWh is plenty for my house. My GEL batteries won't see any load over 1kW, also, after this, not that they had a problem with the kitchen appliances.

iirc, it does mention in that thread you can expand battery.

They do, just people don't configure it properly
Luxpower’s "smart load" functionality, available on SNA (5K+ and 6K) and hybrid 12K series, allows users to repurpose the generator port to power heavy, non-essential appliances (like geysers or pool pumps) only when excess solar energy is available or batteries are sufficiently charged.
Plus you can also handle different time slots in the exact same way, so as per my previous comment it is a misconfigured inverter. Can even configure it through Solar Assistant if you want to

It is not same. On the Sunsynk you can tell it to charge from the grid during a timeslot only if the battery is below a set level. That makes a big difference in finetuning your grid use.

That's how you configure it on the luxpower. 1667604935.jpg

Sunsynk doesnt charge battery, it just uses grid for load when battery reaches set minimum SOC.

Ooooh, that's silly why would you want that? I mean if you're going to tap into the grid, use a bit to top up.
Then again I only ever tap into the grid for an hour every so often nowadays.

It will charge if the next slot has higher SOC setting.

Riiiight, throw more batteries in ;-) I mean the whole point is to use as little grid as possible, not get a science degree in it.

Yes, that's why this one here I set to between 10-20%, not 100% like in the above example.

That would make a bit more sense. I miss my Axpert, you just said yo use grid and it did until you said stop using grid. The luxpower is like hey I want to use grid, push this button that says smart charge and it does for an hour and stops, guess it's only for top ups.

My inverter is still Primary school science. Some here have gotten to PHD lol. But I will say having all the flexibility is still nice to have. Thats where the Sunsync and Deye thrive.

My boss has a 3 phase Sunsync and he got lost with all it can do, went down the rabbit hole only for him to never check the app anymore. He has 6 batteries now and a ton of panels so that could explain it also. Rather than tinker with every setting he just threw batteries at his problems.
 
@wingnut771 I may not have bought a second or 3rd geyser but you did make me buy another inverter.

It’s 7 months of Shitipowha fixed charges being offgrid so won’t affect the payback that much.
