You are so generous. I'm entered 👌

This is great. I'm definitely following this topic!

Try set batteries to 100% for the whole night with battery shutdown on 50%. From my experience if there is no grid then your battery will deplete only when there are no mains until the shutdown value and revert back to grid and start charging. (but I last did any test like this a year ago, so cannot be certain) Test this and share more info here.

I am also looking to add 2x more US3000C batteries to my system. Will let you know what my electrician ends up doing.

I would definitely recommend that everyone starts using timers to manage energy requirmentes Your timer routine sounds pretty much the same as mine: + Pool pump = ON @ 11h45, OFF @ 15h45 + Geyser = ON @ 05h15, OFF @ 06h15, ON @ 11h30, off @ 16h00 It is an awesome feeling running an aircon off the power of the sun on a hot day 🙂

100% agree with you hear 🙂 I use my PV's excess solar energy and a geyser timer to get it working perfectly in sync

Hi @zak2021, To answer those questions: 1. Secondly do you need a CT coil on the grid side? 2. What if you want to feed it back it the grid as a grid tie in system? 3. From what I read the CT coil stops the export of excess energy back into the grid. AM I correct in that understanding? All answers are YES. The CT coil measures the amount of power flowing along your main power cable. It can measure both directions of flow and this measurement is used to allow for a variety of configurations On the Sunsynk timer setup screen: Prevent export power to the grid with "Zero Export". >>> Tick this box to do not export power back to the grid (the CT coil will detect power flowing back to the grid and will reduce the power of the inverter only to supply the local load).  Limit power to supply to only all the house loads with "Solar Export". >>> Tick this box if you wish to export your solar power back to the grid.  Limit power to supply only the loads connected to LOAD port with "Limit to Load only". >>> Tick this box if you only want to supply power to the load side of the inverter.

I know my landis+gyr gemini plc2 prepaid meter detects reverse flow and deducts from my prepaid credits. This is because it has been programmed like that. I am waiting for Ethekwini to approve my SSEG licence and bidirectional metering.

Item Wanted: 2x PYLONTECH US3000C 3.5kwh batteries Packaging Essential: yes Desired Age: 180 cycles Location: DURBAN region Willing to accept a shipped item: TBD Ballpark/Budget Amount: R28,000.00

Item: solarman data logger wifi x2 Age: 180 days online (max) Price: R1600 Payment Method Accepted: EFT Warranty: none Packaging: box Condition: good as new Location: Durban (Westville) Reason: upgraded to sunsynk data logger Shipping: at buyers cost Collection: also available Link: none

I'm still doing research at this stage. Just considering options. I'm happy with my batteries, good for 6000 cycles down to 5% if I am to believe the marketing. Though I only take them down to 15% daily. If I can grab 2 more pylontech us3000c's (second hand) for 30k then that is a much better for me I think.

It is tricky because also the sell rate is cheaper than the buy rate

I thought so. What is the going second hand price for pylontech US3000C 3.5KWH with 180 cycles?

I have 2x sunsynk 5.5k hybrids, and 2x pylontech US3000C 3.5kwh lithium batteries. Can I add a Hubble AM2 5.5Kwh lithium battery to my system, and how would I do this safely?
