Thanks, actually saw in the manual it indicates Charge Voltage as 52.5 - 54 V

Yip, we are on the same page here For now I am running with it as is, until someone can supply more accurate\verified information.

Anyone know the correct\best settings for the Dyness B4850 2.4kwh batteries for Bulk and Float voltages? I see a lot of data on the Pylons, but havent seen a spec sheet detailing these 2 settings yet. OR just not looking where I should. TIA

@ConradDeWet How are things running so far your side? Have you seen any discrepancies between SOC of the batteries in the APP\Web vs what is physically displayed on the batteries? What I am seeing my side is for instance in the morning after running from batteries all night my App\Web would indicate SOC at 75% or 50% for instance. However when checking on the batteries themselves, I can see that only the last led is still green on both batteries(meaning less than 25% capacity and what I am expecting). Late morning\noon I get the reverse. The PV has fully charged the batteries. All lights are green (full) and even the red ALM flashes, which I understood indicates overcharging and is its internal protection. However App\Web still shows 50/75% SOC and charging (holding on to the PV), which at that stage has dropped from 1800W+ generation to <50W generation and indicating as "charging" the batteries. Meanwhile grid still supplies the load of the house! Only way to resolve this is to shut off PV, kill grid and let the batteries take over the load. Within minutes the red led alarms clear on the batteries, app\web shows 100%. Switch on PV and grid again and PV immediately takes over the load again producing its 1800W+. All normal from there until the next morning again.

Thanks, have seen mention of ICC here before. Will do some further reading.

Hmmm, please tell me more. Any docs\url available that details this process and what one can gain from doing this? Thanks

Thanks! Had a long chat with Dan last night as well and he took me through the whole process and we were all systems green in about 30mins! Excellent service and remote support. We setup my settings the same as you mention above. My system was setup correctly (except for the above 3) , it was then just stuck on Error 08, which needed to be cleared and then the batteries needed to balance themselves after some draining 1st.

Same here..Running 2x Dyness 2.4 Lithiumion

Would also like to know the correct config for these 2. Did you get any further?

Thanks and should be useful to others using PylonTech. Any idea if the same would apply to Dyness batteries? Getting issue with new install that runs fine from PV, but as soon as supply switched to Batt, Red ALM LED lights on Batteries and Growatt inverter goes Error 08 (Bus voltage high) within seconds.

Thanks guys. Seems like that at a 1/4 of the price the China option might not be too bad.

Hi All I would like to start looking closely at my current consumption on devices and circuits and by doing this start eliminating high usage items that can be replaced with more energy efficient ones. What is everyone using for this? I saw this and looks like a good option with clamp or even building it into an enclosure where something can plug into it. https://www.banggood.com/PZEM-022-Open-and-Close-CT-100A-AC-Digital-Display-Power-Monitor-Meter-Voltmeter-Ammeter-Frequency-p-1356031.html?rmmds=detail-top-buytogether-auto&cur_warehouse=CN Any suggestions?

Very cool! Would one be able to add this DIY battery pack to a current solution already running Pylontech or Dyness batteries?

Thanks for the clarification and also understood around your comment on the FB post. My questions just started running after I saw the non approved inverter comment, as I have an upcoming installation and from what I understood from the installer was that one can have an off grid system which runs a "non-approved" inverter and which has auto grid backup when PV and batteries cant take the load. Also as long as you are not exporting back into the grid. As you mention above, I have also heard various different stories on this and would just like to not be in the situation where the install is done and CoCT then come and say, nope cant do it and costing me more $$$. Due to not having the detailed design of how the above would function I am taking the reputable installer's word on this.

Any more reviews from Growatt users out there?

Thanks for a great detailed thread. Now just some really noob questions on the above table. So at 60A supply you are limited to a PV array producing max 3,5KVA? (typically x5 or x6 for the amount of sun hours per day). That then feeds your load (and possibly batteries). BUT how does this related to the size of inverter? From what I understood in basics terms, your inverter is your gate, with 5kva being a bigger gate than a 3kva and thus can allow more traffic (load). How is it then that a 3KVA would be fine but not a 5KVA for CoCT?

Would also like to know of someone in CPT as I need to start looking at an entry level solar option.
