Help me understand Sunsynk/Deye MPPT characteristics
Tariq replied to Thunderdolt's topic in Solar Power
The two strings can have different panels from each other, on the same sting panels should match very closely -
what do you have on the second string
-
the inverters listed on the CoCT have had to pass NRS certification, whereas the Axpert type inverters don't have any certification, I think their biggest fear is that these inviters will feed back into the grid, when there is load shedding. The reason for grid-tie requirement is, that a lot of installers were using a loophole to bypass the engineer signoff, which obviously costs money
-
Had the same problem at a clients house, faint glow from the LED lights during load shedding, found out that the neutral-earth relay wasn't working, voltage between neutral-earth was 111 volts, sorted out the relay issue and all was good.

I have a friend with 10 panels on each string on a Sunsynk 8 kW inverter, hasn’t had an issue, he is in Cape Town where winter temperatures don’t usually dip very low. The maximum I install is 9 panels in one string ( Voc 49 volts ), just so that I don’t have problems with warranty, if the need arose.

you still need protection
-
The sunsynk automatically does what you need, you can set the soc percentages on the use timer for eg 90-100 percent during the day ( the inverter will add from grid instead from battery ) and in the evening/night, set the soc on a sliding scale all the way down to whatever you feel comfortable with, so that the inverter uses battery, not grid
-
What panels are you using
-
Remember the Pylontech batteries are 0.5C, so each battery is 37 amps charge and discharge
-
@Steve87, you are right, didn't notice the op saying grid is down
-
Yes,it will
-
The 8 kW is rated at 22 amps per string, what is the current rating for the panels, remember current adds up when paralleling strings, you will have a good bit of clipping
-
I am starting to use the Sunsynk battery with Sunsynk inverters more and more, although it is a bit more in price, but the extra 5 year warranty is worth it to me.
-
@I84RiS, thanks, yes, got it reversed
-
My Pylontech 2000 batteries are 2 years and 1 month old, been cycled down to 20% DoD every day, are down to 95% SoH, also, used as a buffer for partly cloudy days, just wandering, what others are getting

Hi Wilfred, what do you have Tariq

Congratulations, welcome to the solar community and may you have many fruitful solaring days -
In system mode 2, untick “ solar export” , also your grid trickle feed should be set to 20 watts
-
Do you have communication between batteries and inverter, meaning a CAN cable
-
Have 540 watt panels mounted on an ibr sheet carport ( landscape mode to ibr sheet ),water accumulates on some of the panels, probably due to the underlying dips in the ibr sheeting, question is, will it affect solar production

Sunsynk Batteries increases Sunsynk Inverter warranty?
Tariq replied to DannyBoyZA's topic in Batteries
I bought one about 2 weeks ago, it was the 1C battery -
Does the Deye use the Solarman dongle, same as Sunsynk

Sunsynk Batteries increases Sunsynk Inverter warranty?
Tariq replied to DannyBoyZA's topic in Batteries
I asked Sunsynk support in Jo’brg, there seem to be two batteries floating around South Africa, one is 0.5C and the other is a 1C, but having a hard time finding spec sheets, as per Steve st Power Forum store, as far as he knows it is a 1C that they are selling ???
