8KW Sunysk and Hubble AM-2 5.5KWh Inverter Settings

[WhyME]

As per subject my setup is as follows:
8KW Sunysk Inverter paired with x2 Hubble Batteries
Canadian solar panels 455w super high power mono (qty 16)

Would like some advise on following:
Maximum production I have ever reached on my solar production is 15kw(Seems a bit low) this only happened when I moved geyser to solar.

Battery Settings are they correct, my charging amps and discharging amps? would obviously like to protect life span of my batteries but also save on electrical bills as well.

What is maximum I can set Power on System Mode based on my batteries ? Initially had it on 8000 brought it back down to 6500 not sure if its right thing to do.

Any other advise will be appreciated based on my settings attached.

If it's an 8kW inverter then it should be set to 8000.

Something doesn't seem right with that graph with the amount of panels you have.

Can you post your work mode (the screen with the different time schedules)?

Agreed, set it to 8000 and there is definitely something wrong with the production.
My setup is similar and I have 89kWh for April.

I have the 8kw sunsynk and my inverter power is set to 9 000w.

Your battery charge and discharge settings should be 200A. Hubble batteries are 1C rated.

Show your daily graph with production, consumption and battery SOC.

How many strings are the panels split into and which direction are they facing?

89kWh total production for the month? On that graph I have shared mine produced 15kwh for a single day that's when I connected geyser to solar.

What would you guys expect my panels to produce on good sunny day + assuming my load is high to be able to produce at capacity?

On their technical sheet says 100A continus discharge, why 200A does this figure increase with number of batteries ?

MPT1 and MPT2 split equally. I assume this is what you are asking about. The panels are facing 100% correct direction the get sun from sun rise to sunset. North facing if not mistaken.

My best day was 46.3kWh

Fok then something wrong, with my production. Best fay so far has been 15kwh and my panels rated at 7.2kwh production

I think we want you see hourly production and hourly consumption to see when you using load.

Maybe time of use is an issue

Anyone on this?

 

[W@P]

Anyone on this?

Mine is set to 220Ah as each hubble is 110Ah. That's how i was instructed to do by Steve at the Powerforum store

Take a screenshot of the graph showing the hourly figures from the Solarman app.

It increases per battery

Since your geyser is now solar, you're not putting much load on your panels. This is an issue we're all facing - how to increase your daytime load to make more use of your panels.

Next issue is your system mode screen. If you want to reduce your bill, you need to make better use of your batteries. From 17:00 to 21:00 your batteries are set to 100%, which means you're running on grid during peak hours.

You may want to drop that to 60% as a start and see how it goes. But definitely rework your times and battery usage. If you're using high load devices like an oven, air fryer etc during those hours then set a specific time for it to use grid like 17:00 - 19:00 for eg. Also 05:30 - 07:00 is a wasted slot because you're never going to get to 80% - not enough light especially heading into winter, so definitely rework your times to make better use of your batteries...

Rough month almost 200kw

Best day around 29.2




Typical day - I have 6.42kw panels

how is your shade situation a little shade can mean 0% production

how is your shade situation a little shade can mean 0% production

I'm getting nailed by this - the lower sun angle lines up perfectly with some large trees - so my window of production only really starts around 1030 vs 730 in summer
