    MPP Solar MPPT charging issues - Parasitic oscillations in Switching supply

    Shouldn't be a PV voltage issue. The MPPT on these units is rated at 60-450v DC. I've got an Epever 100A 200v MPPT charge controller coming (I've had great experience with the lower power Epever controllers in the past), but I'm a bit annoyed that it has come to this.

    Half price electric cars

    Have a look on YouTube for unsold Chinese EVs! There are thousands, if not tens of thousands of brand new EVs sitting in huge lots in China. Some are approaching 5 years old and now obsolete - not to mention the fact that the batteries are probably completely rooted from sitting for so long...

    MPP Solar MPPT charging issues - Parasitic oscillations in Switching supply

    Further to this.. Below is an audio spectrum plot (taken from a phone) near the AIO. When the MPPT switching goes parasitic/spurious, You can see well defined audio peaks across the audio spectrum and increased noise above 20Khz. Unfortunately, my phone mic only detects up to about 25Khz, but I...

    MPP Solar MPPT charging issues - Parasitic oscillations in Switching supply

    Hi guys, I have a new(ish) 3 months old PIP3024GEW AIO. For the first few months, I was relatively happy with the performance (basically just using the inverter function). At that point, I was not using the inbuilt MPPT charger because my small PV array couldn't produce the minimum voltage for...

    MPP Solar 3024 AIO not going into bulk charge

    For anyone following this thread.. I've been in contact with MPP. MPP comments - "Bulk charge is not activated unless the pack voltage drops to 25v" So basically, unless you discharge your pack to 3.125v per cell (or about 15% SOC) overnight, you will never activate Bulk charge. This Bulk...

    MPP Solar 3024 AIO not going into bulk charge

    Hi guys, I suspect this might be a bug in the MPP firmware?? I have a PIP GEW 3024 AIO. The system is completely off grid and has the following attributes: Battery - 8 cell x 300ah Lifpo4 BMS - Daly 8 cell Solar - 5 x 415w panels in series. Inverter battery profile - 'User' (as all of the...

    Energy-Mate App for MPP Solar LV6548 inverter

    Energy mate works quite well, once you finally get the AIO to communicate with the cloud (subject for another post lol), but there are still a couple of wrinkles that need ironing out. Firstly, there is no ability to set daylight savings time, so your log/data will either be correct, or 1 hour...
