making mistakes so you don't have to...
Can you set to workmode "solar" (not AC + PV)
Probably will fix your issue.
Probably will fix your issue.
ich have it only on Solar!Kann man den Arbeitsmodus "Solar" einstellen (nicht AC + PV)
Wahrscheinlich wird Ihr Problem behoben.
Strange!!ich have it only on Solar!
This first one (D69-3062) does maximal 600v and has an 20A shunt build in.nd I learned, it is important to shut down the complete system and start it again after changing the parameters and than to wait and lock.
Bye the way, my answer to the shunts and amperemeters??
Hello Frank!Good morning Sebastian,
That's an impressive setup.
I have 3 Revo II systems, on a 50 kWh battery (3 X BYD 260ah, one Eve 280AH)
No grid here.
The Revo II is a fine little gadget, for its price.
Absolutely not the best, and not the worse either!
Some of the things you need to be aware of:
- The internal shunts are crap.
Not accurate at all.
- besides not being accurate, it's "modified"..
MPPT will eat the first 100 watt from the solar panels before it will start to work as MPPT. Maximal output is 42-4400 watt, the display shows 5500.....
Up till 3500 it's fairly accurate.
If connected in any wat to the grid, this connection eats 160W. Per unit, always (24/7)
No idea why, and as I live off grid, I can not confirm this, besides that many users have reported this.
With 6 units that's almost a kWh drain every hour.
Add the 75 watt for being turned on and act as inverter, roughly 0.5 kWh..
That's thirsty.
Own energy consumption of 75W is "standard", even Victron 3.2kw uses 50w from the battery with AC enabled (and not used, switched off breaker)
The lifepo4 settings, I would change.
15 to 85 or 90%.
95% is kinda high, as is 30%(!!)
For many installation settings to lithium is good enough.
Strangely the Revo has only S15 as profile (not specifically mentioned in their documentation) not the now standard used S16.
Reason? At time of development they sold S15 lithium battery packs...
4-5 years ago this was the normal configuration to replace 48v lead acid.
Make sure that the settings are enacted as sometimes it does safe, show the correct settings, but still uses the old ones (what would be lead acid as standard profile, 58.4v)
There are better units then the Sorotec Revo.
Outback and Victron.
Grid connect without battery,a whole long list.
Grid Connected with own battery packs, also a long list.
Tesla powerwall
Huawei power
Again, long list.
While the Huawei is impressive on paper and real life performance, you are bounded to Huawei batteries, 800v (if I recall correctly, can also be 600v)
Besides the price (compared to "standard" China cells), making my own 800v battery and being able to write about it (not fried to crisp), I find that dangerous high voltage!!
Huawei does have 3 phase sets.
I guess Tesla will have also.
Victron and Outback will have high quality inverters, lasting decades.
Price for 5.5kw inverter .. (€2500)
Then you need MPPT, (€750-1000) communication unit, and a whole lot more.
Expect about €4000 to replace one 5.500W Revo II.
You will get all the bells and whistles working, good feedback what is really happening.
Victron smart shunts are legendary ...
Remote control and full insights.
€24000 compared to €4000 (?) Now...
That is a lot of money.
Usually buying a few additional solar panels and larger battery to compensate the energy consumption of the Revo, and accept that you will need external shunts to get accurate information (Victron smart shunts for the battery)
Will save you like 15-17.500 euro.
Not sure if it will last decades...
(The Revo II)
Tip: buy one Revo II for swap.
Today !!!
In this setup, all firmware version need to be identical.
While you can update display and MPPT firmware, the controller boards need to be bought new if there is a mismatch.
In other words, if one unit fails in 2-3 months, your whole system will be down, untill you replace 5 boards and one whole unit, because the new unit will have different controller board firmware....
(Okay, you still would be able to use the 5 still working, waiting for the 6 (!!) replacement boards.
Replacement boards aren't guaranteed the same version as your replacement unit.
So you need to replace all 6.
And update all mppt/ display firmware.
(Tip: buy the J-Link from Sorotec as most China clones aren't able to flash the MPPT, leaving it dead till you have a good J-Link unit and reflash it)
Having a spare unit will prevent the trouble at that time, give you time to repair and if needed, order enough parts to be fully operational again. (7 boards in that setup, + the parts that smoked)
For the price it are great hybrids.
Don't expect to get the same level of insight as you will get with Victron.
Only the MPPT (5500W) is already 750-1000 euro....
You do get higher quality for this
Impressive, not Revo II inverters.Hello Frank!
Thanks for Your reply! I will read it carefully tonight. Right now I am actually setting foundation for my 4th string of nine panels. Have to make use of the nice weather we have today on the Swedish west coast. I just wanted to quickly comment about the connection to grid. I have at the point of entry to the building a very precis metering function. Right now the house runs on 100% batteries + solar. At this time the inverters uses 4.5W per phase. Later today I will install the same type of meter on the load panel of the system. I will then be able to see in great detail what the losses will be when just running from the grid, but still passing through the inverters. It will be interesting.
Kind regards
Sebastian
Under construction. But now fully up and running.

Did you get the RS232 communication to work for setting the parameters in the inverter, we can read parameters, but not change them over the RS-232 line.Hi, there is many questions about the working of the REVO II series from Sorotec ( same model as EASUN IGRID VE II ).
After many questions to the Engineers, i finally got mine to work.
General Function - This inverter doesn´t like to work with a PV array with Open Circuit Voltage over 300volts. Be sure you set and configure your array to be under 300volts.
CT Limiting Function
- PV Open Circuit Voltage below 300volts
- having a CT sensor 100A/0,333volts
- The CT sensor must be in the correct direction, load displays ( - ) Watts, feed in displays ( + ) Watts. if wrong, just change the direction of the sensor.
- Working Mode - AC+PV with CT sensor Selected
- Ongrid Mode - Set to OFF
You the can calibrate you CT sensor in the other menu to match you load correctly.
Battery
If you are working with LIFEPO4 cells, in the battery menu , select USER and define Bulk and Float
If you have batteries, and you select AC+PV the battery will act as a UPS, only discharges if the AC power goes off. From my findings the PV only powers loads and batter, it will feed the grid with the remaining power.
I tryed pushing more loads and it got it from the grid, not from the battery, so i assume it is backup only mode.
I also got a software for battery voltage and amps calibration but i haven't tested it yet.
Monitoring
For monitoring, i use Jblance code in a raspberry pi. I got the protocol from this inverter and JBlance manage to put it in the software and it is working fine.
you can use Wifi Logger and the app works ok, but i as looking for more detail, that is what i get from graphana in home assistant.
Any help i can give about this inverter, just ask.
Hi,Did you get the RS232 communication to work for setting the parameters in the inverter, we can read parameters, but not change them over the RS-232 line.
It also seems to have a wifi H/W, but we can't find any settings to activate it ?
Best regards

WiFi is a dongle, as far as I know 2 different types can be used.Did you get the RS232 communication to work for setting the parameters in the inverter, we can read parameters, but not change them over the RS-232 line.
It also seems to have a wifi H/W, but we can't find any settings to activate it ?

Hello Frank!...
As trying to charge the battery with the Revo via a generator...
Will probably blow the unit :-(
...
What is perfect, as long as the Generator isn't connected to the Revo.
