Recently got a Narada NESR lithium battery connected with Infini inverter. There is no BMS comms with inverter, so I manually set Bulk charging (54v) & floating (52.5v) voltages. My understanding is that when battery is fully charged, BMS will stop charging the cells and charging current will...

Looking into a 1000V DC MCB for solar string because string voltage is around 600V. Came across this breaker and it has different wiring recommendation for DC system vs PV wiring (which is also DC), so confused about the reason for difference. It seems its only isolating negative in case of DC...

Jinko solar panel has a 4mm hole in its frame for grounding wire connection. Which size bolt should i use for it? M4 or M3? I read somewhere that M4 means 4mm is hole size and bolt diameter is smaller than 4mm, other sites say that M4 bolt means 4mm diameter and it requires a 4.3+ mm hole size...

The Voltronic Infini 10KW inverter, working non-stop for 4 years, has started making high-pitched buzzing noise. I guess it happened slowly over weeks so didn't notice it earlier. Video attached, turn up the volume to hear it. Its quite noticeable even 25-30ft from the inverter. Are the fans...

Need a cable to connect Narada NESR/NPFC lithium battery to Raspberry Pi 3B+ running Solar Assistant. I don't have amazon etc in my country so trying to find a FTDI chip USB-to-RS485 cable off of aliexpress. Does anyone know which cable to get? My understanding from solar assistant's website is...

Got this DC MCB rated for 1000v and 20a (datasheet attached). Under "Wiring method for ungrounded system", it shows Fault scenarios: If I'm understanding this correctly, if the breaker will only trip if there is more than 20A between its positive and negative. If there is more than 20A...

My assumption was if 1/3 of half-cut panel was shaded then its output will go down by 1/6 only. However, as per this video that's actually not what happens: I have a scenario where the bottom third (in landscape orientation) of the panel would be shaded during winter season. After watching the...
