Ah this is advanced feature na that mostly comes with high end inverters.

Optionally, I think there are third party plug ins that can give you such data too. I'm not completely certain though. Others will give their input.

Pls house where can I get energy meter to monitor energy inflow from my panels to inverter and inverter to load.... Plus history and archiving function to view harvested energy and load trends over time

Thanks

Pls is there any third party plug in device that monitors the inflow of solar energy from the panel to inveter that can be recommended.... I will like to acquire it and also if possible logs energy supplied by inveter to load over time.....

Referencing your initial post, you mentioned being unable to set the bms protocol, does your battery come with communication port for such? And the inverter too? (Small battery packs and inverters almost never come with it, usually you just need to know the bms brand your battery came with, download app, connect via bluetooth or wifi and adjust if allowed)

You also mentioned being unable to view harvest data, you're supposed to be able to view that from the typical inverter interface when you toggle the u.i using either up or down arrow. (Most of these stuffs can be sorted by using the inverter manual).

For your third concern, your inverter self-consumption is quite high for a 24v hybrid inverter compared to most out there. You can try to search online to know if this is normal for that brand of inverter.

My inverter do have some data as per PV array voltage, PV array current, PV array power and load.
But it doesn't log the data it only display instantaneous values only. I cannot view the past events, graph etc.

If you're able to set up float from inverter you should also be able to set up charging current from the inverter interface. Kindly pick up your manual to see how to set up grid charging current and adjust to your taste. What is the capacity of your battery?

Grid was preset to 50A, I refuced it to 20A then later 10A. I later disconnect the grid supply due to prior mentioned high standby consumption and inverter fan running continuously when grid or panel power is active.

The charging max input current from all sources during charging is set to 40A Vs 100+ Amps that the inverter can support

Good day my fellow comrades. I joined the solar energy generation path due to NEPA aka PHED showing me too much shege, especially sleeping in darkness for several nights due power outage. I don't have much knowledge about solar energy. I was just asking grok for most info and suggestions about my intended setup before now.
- I have 4 pcs of jinko 535w bifacial connected in series
- I have Jsdsolar pure sine wave 4kva - 3.6kva continuous rating transformerless inverter (hybrid)
- 1 pcs of Itel 24v lithium batteries
- We couldn't install the thunder surge protection device as my apartment has no earthing rod.

My installer installed the solar panel on the roof and did the wiring and tried activating the inverter and battery but couldn't. He got exhausted and left promising to come back later.

I however read through the inverter Manual and configured the inverter settings which was about 44 different settings in total. The system came on and was running on steroids during charging and testing on home loads.

I later disconnected the mains supply line to the inverter as I observed that it like charging the battery rapidly through the mains as I don't want my NEPA unit to be spent charging lithium battery. Also the Inverter self consumption with no load on NEPA or solar panel is ranging from about 70w to 100+ as monitored Via inverter and calculated using measurements from digital multimeter meter.

The inverter is actually very smart and will cut it power off if it detect abnormal condition, wrong connection, surges etc... Sha I de try de careful I know wan roast the machine...

My concern in this my setup is that
- I couldn't set the BMS protocol settings, all attempts to romance and try different protocols was abortive, I had to latter switch off battery monitoring via BMS protocol with ethernet cable unplugged for peace to reign.

- I am unable to know how much I am harvesting from the sun via logged meter interface and to see the performance history of the system over time.

- How do I reduce my inverter high self consumption when solar panel input or mains input is active.

My battery float settings was initially 27.6v and I later brought it down to 27.4 volt though AI recommended 27.2V. My battery cut off is 23.9v.

My house load is
- 4pcs of 15w bulbs
- 4 pcs of 5w bulbs
- 1200w akai microwave
- 43 inch Samsung tv
- 1000w Phillips dry pressing iron
Samsung small fridge running load is about (100 - 120)w
Pumping of water from borehole once in a day for 30mins (pump capacity monitored from inverter is 1.1kw with a rewinded coil.

I need input from this community on how I can maximise the use of the system, my goal is to run on full battery mode for at least 2 days without NEPA or adequate sunshine. I want also to be able to monitor the system performance down to if possible battery BMS behaviour in real time or near real time..

Pls inputs and advise from Everyone is welcomed.

Do you still build 24v 7.5kw Lithium cells.

Mrreed:
Thanks for the recommendation chief.
Yes, I sell cells too, they are easier to sell than the couped ones.
3 2v Eve 150ah 57k
3.2v hithium and Rept 280ah 82k

Pressing the power button and the voume down key (at the same time) captures the screen and saves it to a foder "screenshots" in your gallery.

Thanks man. Here are my shots.

Indoor with nepa lighting.

I got my Tecno L6 three days ago. The phone is nice and ok. The pics taken from the camera is sharp and Crisp clear despite its low resolution build. The phone is fast and does not lag at all despite its humble spec and hardware. I de envy those where their battery de last for 15 hrs on heavy usage. Mine last very long though its yet to match theirs. I began using mine after charging it for upto 85% for the first time. I did not know about the initial charge precaution maybe thats why I no fit get him full potential. I would like to post the battery stats pic but I don't know how to snap and post screen display, Pls can somebody guide me. I also root the phone yesterday using king root.

Hmmmm
