lots of manufacture, we are one of themI'm curious who manufactures it for Y&h
Am also in the same problemyou can also ask Y&H for unbinding. they will take some time. All of china is on holiday for Chinese new year.
its done, unbound the device based on the code you gave meAm also in the same problem
Am also in the same problem
I will visit the site tomorrow and try it out againits done, unbound the device based on the code you gave me
Mine worked after the unbounding thanks to @YurenHi! How's the inverter doing? Did you sort out the dongle? Also, may I ask if you know if you can parallel these units?
TIA

Am faced with the same issue, when switching from battery power to grid. The changeover is erratic I will loose power for about 5mins.
I have a DIY lifepo4 eve cells, I set the low battery on my jk bms at 2.5v and on the inverter as 2.7v. Still the transfer is never smooth
Can you please share how to configure the SmartESS setting? I follow the exact procedure from the user manual but it didn't work.Mine worked after the unbounding thanks to @Yuren
Do you work for Y&H or SRNE?lots of manufacture, we are one of them
am having a different problem on mine, connected 8 x 450w 49voc panels in series. with breaker off, voltage reads 367v on top of breaker, but drops down to 92v and 187v once the breaker is flipped on...and thus unable to charge batteries!. AC charges ok. any idea what could be going on?...anybody.Having used this inverter for a month I would not recommend it - unless LOW-cost is VERY important to you.
Issue 1
The switch-over from supplying power into the grid to reliance on your battery is messy.
It seems there is no way to do this except for manually disconnecting from the grid. I tried using a WiFi-timer-switch-meter which worked ... sort-of.
The power 'hiccup' resulting from disconnecting from the grid while exporting, sometimes caused 3 downstream (earth leakage) breakers to flip off.
At least grid-disconnection forces the inverter to use the battery, rather than drawing peak-rate power from Grid.
The only way to prevent breakers from flipping was to disconnect the PV panels before disconnecting the grid.
Reconnecting the PV without the grid connection is fine; I do this in the evening to make use of the sun at dusk.
Issue 2
In the morning the PV panels charge the batteries at about 4.5KW (Max). Towards mid-day I switch on the electric hot water booster. The PV immediately generates 7.5KW and lowers the battery charging rate to use the surplus power.
Issue 3
It seems the maximum power that can be exported is around 7KW despite being sold as a 10KW inverter.
Do your search using the original name MPS/V MAXI'm curious who manufactures it for Y&h
seen, but they might not be, as nextpower sells is cheaper at 440 USD. am in talks with anern as well, and if theirs turns out cheaper...will give it to them to be the OEM.Do your search using the original name MPS/V MAX
This inverter is not a real 10.2kw, I have it and PV input, battery output and ac output is maxxed at 8kw~. Unfortunate since it is marketed as a 10.2kw and says it everywhere. Tested the output and at 8kw+ it went overload and shutsdown after a few seconds like the manual says. Anyone know a real 10kw output hybrid inverter? I run everything on my system and I do mean everything
oh really, just 1 mppt?. the manual says 2. if truly its one mppt, then one may run into issues if you send diff strings/voltages to the different mppts. am presently having an issue on mine panel voltage before breaker reads 370v, but fluctuates between 90v and 202v once the breaker is turned on to send solar input to the inverter. tried both mppts. issue persists. 8 x 450w 49v voc panels. tried both mppts, and issue persistsView attachment 163164
Also it only has 1 MPPT for 27amps max, it has 2 PV inputs but internally it connects each string parallel to the mppt
Yea, I noticed it was 1 MPPT at 27amps when the guys first install my system assuming it was 2 MPPTs and my max of 9kw was only going to a max of 4.5k-4.8k, When I told them it was 1 MPPT at 27amps they reconfigured the connections to go 400~v-21amps and now it kinda works, my peak was like 8.1-8.2kw but regular generation on a sunny day is in the 7kws, kinda unfortunate but better than 4.5-4.8kw. This looks like a typical chinese clone and is made by soooo many people (or reselled), I think first few pages said the manufacturer but im not sure who it is, I have been buying chinese imported stuff for 15+ years now and I can never trust the manuals, many typos and missed information most of the time lol but hey I know the language barrier is pretty big. I'm thinking of going the Megarevo route cause a 10kw one is around 2500USD shipped to Puerto Rico and its approved by my energy company to be net metered, sucks that its 2500+maybe 1k extra to do the net metering preparations, I aint rich LOLoh really, just 1 mppt?. the manual says 2. if truly its one mppt, then one may run into issues if you send diff strings/voltages to the different mppts. am presently having an issue on mine panel voltage before breaker reads 370v, but fluctuates between 90v and 202v once the breaker is turned on to send solar input to the inverter. tried both mppts. issue persists. 8 x 450w 49v voc panels. tried both mppts, and issue persists
the specs on yours is similar to what is mine. the also dropped the ball on the dc cutoff voltage on the dual input, range is only 40v to 46v--quite useless.
bought mine from powmr, though nextpower sells exactly the same unit. any clue who the original manufacturer is?
