Growatt SPF5000ES Offgrid 9kw DIY Solar Project
Pink7 replied to Pink7's topic in Alternative/Renewable Energy Forum
Today my units started charge as normal after i change: 05 Battery type from "Use2" (who Growatt want its user to use) to "Use" who much user say better to use. Use2 have a complicated way to try manage parts of the charge... This is a quite common issue for Growatt and some similare inverters. Create issues like Inverter not start to charge or stop to charge. Who wants details on this just google: "Growatt - Odd behavior" Pink -

Well the BMS does manage the battery in normal situation. Just to be clear so no misunderstanding: communication vs no communication in this case is related to use com port on Inverter with a compatible BMS and battery not just voltage per cell as ordinary BMS setup ( as I have) Here is more on the issue Pink -

From Manual: User-Defined 2(suitable when lithium battery without BMS communication)If “User-Defined 2” is selected, battery charge voltage and low DC cut-off voltage can be set up in program 19, 20 and 21. It is recommended to set to the same voltage in program 19 and 20 (full charging voltage point of lithium battery). The inverter will stop charging when the battery voltage reaches this setting Pink -

Yes.. But inverter seems to stop charge at a certain voltage level when it calculate battery to be 100%. When restart inverter it might adjust to 75% battery level and continue charge. Pink -

Had some inverter restarts today after try default charge voltage.Now im back to lower charge voltage as i just remembered i had this issue before and solved it with lower charge voltage to not trig inverter to think battery full. Pink -

Lately my inverters at times do not charge by either stop charging or like today just not start up. I took some screenshot from my JK BMS just before and just after restart inverters. When this happens and i restart inverters ( not BMS) charge start right away. Any one have some ideas what can be reason for this behavior of the inverters? Pink -

How about a solar car port on a budget?
Pink7 replied to Crossy's topic in Alternative/Renewable Energy Forum
34k for Deye must be great value. Look like prices in Thailand on Inverters getting better..I saw the Growatt was at better price in Thailand now also. Pink -

It feels great when waiting for the right offer is rewarded. Pink -
yes i have order a manual tool. I do not see space for a drill there. Pink

Yes, I will add a new valve. I have just ordered an extractor tool on Lazada that i will try use to remove. Pink
-
Tried some hours to find a way to remove last part of the broken valve in the bathroom wall. Any ideas? I have suggested to weld a steel pipe to it to remove but was told here its impossible to weld on. Pink
-
Yes Crossy have some point on this. Growatt is a midway solution.. First i was tempted to go cheaper but I very happy i paid a bit more and got growatt. I think prices now are mid 20k or so.. Pink

I was looking into same type inverters and also looked into that size inverter but ended up with 2 x Growatt 5000 and very happy with the decision. Pink

Battery pack, fire detection and management?
Pink7 replied to Pink7's topic in Alternative/Renewable Energy Forum
Yes i have set JK BMS temp sensors on each breaker so it will stop charge/discharge if hot. I did see some limitation because of the parallel connection will still feed some power to the hot breaker. I will try find a stand alone sensor with alarm/warning if hot. Pink
