The inverter will get all other data directly from the BMS. You can check everything by going the the BMS page in the Sunsynk menu thanks, but the inverter more that 3 minutes to power the load, is that normal, i am getting F56( low voltage error) batteries are fully charged, my load is around 2.5 kw the inverter cant run for more than 10 min.

Am not fully sure I understand what is happening Can you please post pictures of your menu settings for Battery and BMS? And I assume that the BMS of your Pylons are linked and that the Master is connected to the inverter?

The below are the menu pics, when grid power goes off the inverter takes 3min switch the load is that normal, and in general it cant run a fridge or borehole .75kw, it will throw error F56 and cuts off, then wait for more 3min to comeback and switch the load, my old Meccer was just seconds to switch from Grid to Battery or vice versa.
November 15, 20223 yr If you have 2 of the pylontechs connected then you should increase your Battery Capacity to 150Ah (75*2). Are your batteries connected to the inverter using the CAN cable? What settings do you have on your grid settings page?

Ok. A few things: On the BMS screen you can see that it gets the correct charge and discharge values (74A) from your batteries On the Batt Type screen, please change both charge and discharge values to 74A and as @mzezman wrote capacity to 150Ah. The info from the BMS should override the charge/discharge values that you have set, but better to be on the safe side Error F56 appears to be caused by a low DC bus voltage, which can be caused if the load is higher than what the batteries can provide. See here and here. So if your load is more than 3.5kW while running on batteries (or when the power goes off), the inverter will shutdown and take a couple of minutes to restart. It sounds like this might have happened in your case. Otherwise changeover from grid to batteries should be completely seamless (other than a brief flicker in my LED lights I don't notice it) Could you maybe please post a picture of the Battery Shut Down page? Just to make sure that there are no funny settings there 6 minutes ago, mzezman said: Are your batteries connected to the inverter using the CAN cable? Judging by the photo of his BMS screen, the inverter seems to have comms with the Pylon BMS

Are your batteries connected to the inverter using the CAN cable? What settings do you have on your grid settings page? Yes, I have two Pylontechs. I set the top one to be the master, but I'm not sure what the deep switch settings are. The batteries are charging differently, as you can see, the top one has three bars and the bottom one has two. Last night, no battery was charged when power was restored, so I'm guessing it's set to USE Timer on the Inverter Mode. The battery photo is attached. Please let me know if you think this is where I'm going wrong..

Please let me know if you think this is where I'm going wrong.. The dip switch settings should be covered in the manual... were you able to set the total capacity to 150Ah? and did you get a chance to enact @wolfandys suggestions?

Your settings are totally wrong lol. Batt capacity should be 148Ah.Charge amps should be 74A and discharge amps 74A. The reason its taking 3 minutes is because you are overloading the set parameters. Signal island mode should be ticked and make sure you have the earth neutral bond relay. Grid reconnect time should be 60 seconds not 1 second.

Agreed - thanks 3 hours ago, Petsvo said: The batteries are charging differently, as you can see, the top one has three bars and the bottom one has two. Can you please post a picture of how the positive and negative connections are wired on your batteries? It should be one of them to the top Pylon and one of them to the bottom Pylon, with the short bridges between the Pylons for the other connections. That will ensure balanced charging/discharging.

No need to change anything The least I can say is that this is not an efficient inverter because it can only run lights with 2 pylons . I can't even run a fridge or microwave for a minute, and my borehole is even worse because it can't be run with the inverter it will trip. I've followed all of the advice and will rather install my MKSii Axpert/ Meccer back. In my opinion, this is an overrated product very unstable

In my opinion, this is an overrated product very unstable Then something is still wrong with your settings or your overall setup. With 2 Pylons you can supply up to roughly 3500W without breaking a sweat (not for a full 2h though). So for your fridge it is absolutely no problem. Microwave and borehole pump depends on their power draw as well as what other loads you have at that moment. You have very good components, which when properly set up will give you lots of joy. Don't throw money at changing out the components - get everything set up correctly. I have exactly the same components and my system runs rock-stable. Either get someone that knows what he is doing out to check your system - or post pictures of everything here and we can try to provide remote support
March 11, 20233 yr I finally got my sunsynk running it has been running for months now, but yesterday it just cut the power off. Battery Soc is at 85%, Grid is on, the PVs are on. All settings have not been changed but it cant go on Normal Mode, what could the problem

It does seem a setting or 3 is still out of place. Glad to see you at least got it to work better than in Nov when you wanted to ditch it in favour of your Mecer.
