I suggest you get someone with experience to help you, if you in Johannesburg contact Steve87.

That's a useful device.. Link please?

Are you using the 'use timer' function as well, where you can set the SoC based on the time of the day etc

If you using emulated BMS that means you don't have comms between your inverter and your battery. Your SoC is being estimated with emulated BMS, your inverter is probably in USER mode ie voltage based control which has been set manually. So you won't get battery temperature either with just the inverter cable. From what I remember (having had a shoto before) they were very difficult to get the inverter battery coms running with a kodak / voltronic inverter. Not sure if that's been sorted out now. -- Although, even if you have the inverter battery comms set up correctly and use the Lib setting on the inverter, by connecting solar assistant to your inverter you will not necessarily pick up the battery temperature depending on your inverter. -- But : If you get the direct solar assistant cable to your battery then you would pick up further stats.

Call / email powerforum store, they will have details for reputable installers. Phone them and ask if they install neutral earth bond relays and the CT coil... Ask if its important ...(just to assess their competence)

1. You should be able to return the pi, https://www.pishop.co.za/store/returns-policy, within 14 days of delivery, it's still sealed. 2. Email pierre at solar assistant, they should be able to cancel and refund your software only order since you ordered the full package from them now

Panels work all the time when they can... If its cloudy or raining, and panels cannot supply enough power, then that setting is so the battery will provide power as well, till it drops to 60%. Then grid will take over

@Michael37 @MichaelV37 where are you based? Just get one of the recommended installers here to sort your stuff out asap. Delaying will further exacerbate the problems you face and will damage your inverter. If you in jnb give @Steve87 a shout. He specialises in fixing incompetence ☝️

You may pick one up on https://carbonite.co.za/index.php?forums/robotics.208/

Simple... ask them about the CT clamp and the neutral earth bond relay.. If they not gonna install these, stay away

Haven't used them obviously

Seems to be a bit of confusion on this, on a FreedomWon battery, where the battery has a built in breaker, is an (external) fused battery disconnector still required? Or Is it deemed good practice, or not at all ? With multiple batteries it becomes quite a significant additional cost. Anyone care to provide a concrete answer on this matter? --------------------------------------- FreedomWon themselves say its not necesarry as their batteries have a breaker built in. As per their installers manual as well, https://www.freedomwon.co.za/wp-content/uploads/Freedom-Won-Lite-Home_Business_52V_Installation-Manual.pdf However , according to an electrican this is required, as per the following draft regulations: According to the electrician, EXTERNAL means not built in to the battery / inverter . So even the PV strings should have an isolator, apart from the built in isolator the sunsynks have. https://powerforum.co.za/topic/9976-latest-regulations-legislation-for-pv-combiner-box/

Is there any way on the sunsynk to get the inverter to charge the batteries to a maximum percentage of say 80%, thereafter feed the remaining pv back into the grid? Currently only possible at 100 % SoC as far as I know?

Check if the CT shows on the grid info page like below

Is your CT coil installed, correctly?

Edit : duplicate post

Say for example with the sunsynk 5kw, will it be possible to have say 10kw on the non essential circuit (ie no limit from the inverter size) , and will doing this trigger an AC overload fault?

@BritishRacingGreen

Try Mr @Steve87 Excellent installer, super after sale support, no cutting corners

Go sunsynk inverter with sunsynk batteries to match. No issues and 10 year warranty on all items, with local support
