All things Sunsynk (Deye, Inge, etc...)

Solarman & solarman business look fine. Not seeing any export on the inverter either which is why I thought it might be an app issue. Inverter is carrying non essentials fine and not seeing any export on the inverter other than small momentary exports on big load changes. Which I think is normal reading through the various threads.

What is your CT reading on the inverter screen?

I am looking to get new batteries at the end the month. I am looking at two options:

1. Sunsynk 5.32kwh
2. Volta Stage 1 - 5.12kwh.

Any reason to pick one over the other? Leaning towards Volta at the moment, mainly due to price.

Going to give my current battery to family or sell it. Will see how it goes.

They seem to be almost identical batteries so I doubt it matters, just get which one you're willing to pay for.

Volta is being a bit misleading with their advertising though, they tout that their batteries are 1C and state that you'll get 6000 cycles at 80% DOD but in reality that 6000 cycle number is based on 0.5C, just like the Sunsynk (who are upfront on their specs page about this).

Can someone that has a connection directly to their batteries (which shows Cycles), please post that number and the total Discharge/Charge number according to the inverter stats?

I want to see how big that correlation is, for the little stats dashboard I'm building. (I don't have Solar Assistant)

Doesn't it depend on the battery?
Freedom Won told me to take the BMS stats from the battery itself and divide by 2 then multiply by 0.8 to get cycles.

Yes, it would depend on the battery, but most are around 100Ah, so it should give a ballpark (if you include how many batteries in the system).

In theory if I discharge around 5kWh (even in multiple periods) and charge it back, that should be one cycle, right?

So you should get a ballpark estimation of your cycles by looking at your total discharge.
 
Good day all. Some help please. I have a sunsynk-5k-sg01lp1 inverter. We sold our house and moved with the inverter. However, we realized after taking the inverter out of storage that the wall bracket was still left behind in our previous home. Unfortunately we are unable to go back and get it as we relocated. Any ideas..... where I can purchase a spare bracket please ? Thanks.Sample of wall bracket.jpeg
 
Least exciting post in this thread: After long consultation the Body Corporate where I live installed a battery/inverter as a UPS for the lights/gates/electric fence (bonus plugs in the garages).
Deye 5kW hybrid inverter, Hubble AM2 5.5kWh battery, wired into existing DB (no solar).
Most of the functionality is overkill for what we have, but it should be a stable long-term solution.
Power draw with all lights on (and gates charged) is 0.72kW, which gives plenty of margin for load shedding.

P.S. The installer says warranty claims on Sunsynk are a hassle, so he has stopped using them.

Congrats…May I inquire about the rationale behind installers selecting AM2's over AM5's, even though the AM5's utilize LiFePO4 technology and come at a slightly higher cost?

No specific reason (maybe stock or price gouging). I didn't get into a detailed discussion, as our use-case is marginal. Mitigating factors such as lack of solar means the battery will cycle less, mains charging means SOC will always be high. Load shedding in CoCT (Steenbras) currently has a limited impact. Typical use case will be 2 hours of lights (1.5kWh) and 22 hours on standby, with extended battery life-cycles.

Discharge it a little every day anyway. Keeping it full isn't good for it's life either...

I understand that in principle, but with the current configuration it's difficult to schedule an automatic discharge. Anyway I am 99% confident that Eskom will take care of that particular problem on a regular basis...

Other option is to set grid charge to 90%. Given your consumption it'll still allow for ample use and be slightly better for the battery.

I would imagine that it is charge rate. AM2s are 1C batteries, allowing the 5K Sunsynk to charge them at over 100amps. This means that the battery capacity can be recovered quickly between load shedding cycles, even at stage 8 ( where we start to see 2.5 hour gaps between load shedding cycles).

There is nothing wrong with NMC, the same chemistry is used by the Tesla Powerwall which is considered the gold standard. There are also some 4th gen NMC batteries available today that give excellent performance.

The inverter should have stayed, it is considered a fixture. Give it back.

Did you remove the curtain rails too? :rolleyes:
