Anenji inverters - 11.2kW parallel system for only £900

[Anenemy]

I would like to start by saying that im very new to all this but surly a 1.5KW battery supplying power to a 3.6KW off grid system even with 2Kw of solar panels is going to be flat after 70 minutes whilst charging a car?

I purchased an Anenji 8.2KW inverter and 5KW battery powered by 2.5KW of Longi solar power, for an off grid caravan setup. Havent set it up yet mind as im still working out what bits i need - fuse sizes, switches and cables etc And yes 8.2KW is too big for a caravan but hopefully its not going to be over strained so should last longer?

Sorry, just to make it clear(er): The battery has a capacity of 1.5KWh, PV power was as low as 0W to max 1.6KW. EV charging is very special because of:
(1) Communication exchange between EV and power source (AIO), source and transition resistance, safety checks, overheating of plug etc. and
(2) Minimum charge power of approx 1.4 KW (6A, 240V) because of the efficiency degradation of the EV AC/DC inverter.
(3) Power interruptions or any other interference/disturbance don't produce a restart of the system.
Given the circumstances of max 2KW solar power (from garage rooftop) and available solar power in Germany use of a battery is mandatory.
My (all?) Anenji 3.6 AIO would only start the EV charging process after several attempts, but shutting down the AC output after some time though there was enough power from the battery and the solar part.
There were no problems supplying other loads (hair dryer, lamps), I went crazy searching for the rootcause (grounding? etc), finally concluding that there is something wrong in the Anenji AIO (software?). My EAsun/SRNE 3.6KW AIO is now running smoothly in my setup.
Interested to know if your Anenji works with EV charging! Good luck for your project, your battery capacity is ok!

Im very new to all this and Anenji documentation is very basic.
Ive now temporarily setup my 8.2KW inverter and the 5KW battery, but im a little confused as to the battery management.
I have the WiFi Plug Pro 05 connected to the inverter as recomended but as SwitchDoctor says "runs fans on full" when doing very little.
As the inverter has only the one comms port, surley we sould be connecting the battery to that and then the WIFI plug to the battery?
Ive asked Anenji about this but so far no reply from WhatsApp or emails. I tried a cat5 cable between them and attatched the WIFI plug to one of the batteries RS485 ports. Plug just didnt start up and no idea if the inverter could see the battery any better. So really not sure what to do.

Update now i'm six months in with my 8.2kw setup and I've completely given up on using flooded batteries with my Anenji hybrid inverter.

For now i've come up with a solution that seems to work for me where i have grid power and might help others:
I've given up on using flooded batteries with this unit -
it just doesn't work and draws more power overnight than you gain.
it flattened my batteries down to 36v = 8v each on several occasions - this could ruin my cells
it ran the fans all night when it should have been doing nothing
I saw the battery draw go to over 80 amps on occasion which might be ok for LiPo but not good for my leisure cells.

I've reverted to running it as a standard Grid-Tie unit - reversing my topology and not running hybrid.
It's now behaving itself; no more overnight fans, it sits quietly when not working.
It's LOTS more efficient; I've exported 60 units to the grid this month as well as covered my daytime base use.

I'm sure that Anenji's issues are with very poor programming which leaves me a little worried for the summer months when i'll be pushing 6kw of solar through it. Without software updates nothing is going to change with the unit i have so i'm going to have to work with it but reality is that I'm scanning the market for a 'better' inverter that does what i need and will probably demote this unit to running further PVs on my garage in grid-tie mode.

I'm not promoting myself as an expert here but IMHO you're concept is good; the RS485 devices should daisy-chain but i don't think it'll work with a standard cat5 cable - the connections are wrong. I'm sure with a bit of googling you could simply cut the cat5 in half and work out which 3 wires you need to connect - Rx,Tx and Gnd. (or order RS485 cable next day from Amazon)

Is the Anenji G99 approved for grid-tie and on the ENA Type Test register?

Hello Guys

I would like to ask did anyone actually Order from anenji.com (recently) and how did it Go?
If it went Well how Long did you wait for Them to ship your Order?
I Made payment 4 days ago and they confirmed that they receieved, told me they Will ship and now they dont ship nor reply to me.
I tried different Email they replied within minutes.
I am verry sceptical about all of this...

Thanks

It was the same for me, I didn't even get a confirmation of payment. But finally after 14 days it arrived.

My order directly with Anenji went well. Inverter arrived within 4 days. Battery took 60 days.

But after sales contact is a joke. No reply on whatsapp. No reply to emails. No reply on the site support. Was just asking how to connect the battery to the inverter with a comms cable and had the wifi dongle working at the same time. Ill work it out eventually, but not today.

I did have an issue over the weekend. The inverter decided that the battery was to low to charge. It was flashing up 04 (battery too low) and then bp (no battery connected) I eventually managed to get a 24V charger and used that via the inverter to charge up the battery. Connected to one side of batteries for 24V and then the other side. It worked, the inverter saw more than 48V and started charging the battery.

For future proofing, anybody know of a small MPPT controller that would output 48V and accept 5 panels x 39.43V (197.15V) @ a max 14 amps. Got no idea if that's relevant or not!
Using one of these I can bypass the inverter and just charge the battery directly.

Or would an ebike 48V power supply be ok to charge the battery pack?

Hi Forum. Bought an Anenji Hybrid 6.2kW 48v Wifi inverter, £285 delivered from Germany.
Have it running on Solar, Battery and Utility.
So far works ok but have a question to ask...
Cant access options 43,44,45 SOC battery settings.
I tried [05]USE and AGn but the SOC options do not appear.
Wondering if they are only for Lithium LI2, LI4 ?
Any help appreciated please.
Thanks. Pete

Hello ! How is your inverter now? Still ok?

Did it all work out OK?
I'm considering buying a 6.2Kw system and 5K battery for an off grid caravan power supply. With the current sale on it should work out cheaper than a pylonteck 5000 battery alone.

No. ANENJI are awful to deal with. I’m too exhausted by it all to recap the whole saga but the current situation is that after installing replacement main boards, I have all 3 inverters and batteries working. The work fine in individual single phase setup or parallel single phase but so far we can’t get them into 3 phase parallel. Everything works fine until you go to menu item 28 and try to select 3phase output mode… it won’t select when you press enter. It will only let us select single phase parallel.
The other problem we have is the rs485 communication connection to the battery array. It doesn’t work wired the way the manual and Anenji say/ the pins should connected so the icon showing connection doesn’t show.

I will pay good money to anyone who can solve this. I’m at my wits end, really am

Hello
To change the operating mode from single phase to three phases, the inverter must be switched off at that time.
I managed to do it this way:
My inverter is connected to the battery. I turn it on with a toggle switch. After switching it on and after booting, I turn the toggle switch off. But the screen is still lighting up and it is possible to enter the settings menu. In this state the inverter can switch between single phase - parallel - three phase.

As for the rs485 connection - the protocol on the inverter and on the battery side must be coordinated. In my case I used Pylontech protocol both on the inverter and on the battery BMS and on the BMS I chose the baud rate 9600 (I have JK BMS)
