Native Homeassistant energy dash works I've set it up via mqtt broker that I also use for my paradox alarm

with the latest firmware   SUB mode still feeds to the grid if PV wattage reaches 2000w and more sometime not I've had 2600w of pv with no feed to grid
just wish the had something in the firmware to turn Grid feed in off (SUB mode)


only Utility mode and SBU mode  never feeds into grid
utility mode will charge the battery and send surplus energy to the loads   but once battery is full the MPPT goes into standby  only to be woken up if you switch to SBU

so  i only run SBU now   have 2X Pylon US3000C batteries   and 2 strings  with a total PV of around  4000kw so  SBU mode works fine for me
I only use SUB if the load is high and pv low due to rain etc.
then if there's high load but partly cloudy  i use utility mode if i want to charge the batteries and prevent prepaid meter trips.

then SBU mode as much as possible the rest of the time (90%)
 

 

Yes i updated last night and i can confirm i've not had any issues yet looks like 90.19 do not feed into grid in SUB mode.
 
 

It turn out that firmware version 90.11 disables SUB mode so the inverter then only have battery mode and utility mode
My inverter came with 45.02   and i just flashed 45.04  SUB mode working again and ill test with this firmware.
i would think that they can adjust the amount of utility power draw to prevent a cloud moving away from the sun to not send power back to grid 

Ok so i flashed to latest firmware from https://www.ostrovni-elektrarny.cz/support/Axpert/FW/
 
MAX7200_Main_CNTL_DSP_90.11 and  MAX7200_RemotePanel_Reflash_MCU(12.03)
and since the update SUB (line mode) no longer feeds power into grid.
will monitor but seems that the issue was fixed with a firmware update

Solved this issue  right is the Battery  left inverter 
so battery pin 8  to inverter pin 3  and battery pin 7 to inverter pin 5

Hi CaTcH21

whenever i want to charge batteries i use my Hobby charger, true they will take long to fill up a large Lithium but they can charge pretty much any type of battery
I use my hobby charger to do a equilize charge over night  on my lead acids every 6 months or so

 Where did you buy the 100AH lithium cells ?
 

My solar setup 

After almost buying SONIC or OMNIPOWER Gel batts  
I started to feel rather go with tried and tested so ive ordered Trojan T105RE batteries at R2491 incl vat per batt
Arriving Next week

R5500 excl vat from sonopsolar 

There is a 200AH 12volt   Trojan J200-RE  but ive not seen it locally yet 

Any places in Cape town that buy back old batteries by kg?

Im only using the batteries for the odd power outage and wile on solar during the day to pick up any shortfall in production when it rains etc.
So im not really going to cycle very deep every day. so it guess for usage like this the Trojans will last 8 years or so.
 
 
 
 
 
 

It sould yes 
There's guys in Australia that have hooked up 9 250W panels to a Axpert MKS plus 24V 3kva in 3 strings of 3 panels
if the output from the panels gets more than 1500W the MPPT controller will just take what it can it wont go over 60 amps.
Thanks to EDMUNDP im all set up   http://www.pvoutput.org/list.jsp?userid=50978
