  • Found a website interface, for the MPP Solar WatchPower app data

    I hadn't seen this posted, so if it's old news, I apologize. Recently I was without my phone for a bit and wanted to check remotely on my setup at the cabin. I wished there was a simple way to view the info I see from the WatchPower app on my PC. I went through my router logs to see where...
  • What is a cycle?

    Batteries often advertise a certain number of cycles - many Lifepo4 are in the 3000 to 6000 rating. But what defines a cycle? I get it from a full discharge to a full recharge. But what about 'cycles' that drain 10 or 20% of available energy, and then gets recharged. is this also a cycle?
  • I think I almost have a powerwall for backup power, well sort of?

    I have a simple setup I built to power my small garage/shop. All in One MPP LV2024, and 6 24v 100ah backup batteries (14.4kwh) with 800w of solar. Works great, meets my needs. It recently dawned on me, that if I added a second LV2024, and a parallel kit, I could have a powerwall for home...

  • Mop LV2424 inverter cycles 120v to 0v back to 120v every few secs

    This only happens when powered by batteries. It’ll send out 60hz/120v for 3 or 4 seconds. Then drops to 0 for a second or two then cycles again Batteries are at 27.6v. Any ideas?
  • Every night at 11pm my Grid wattage spikes

    At my remote cabin, I've seen that each night at 11pm, my grid usage spikes. I've looked through all my MPP 20204's settings and can't figure out what might be triggering this? It's not from unexpected load Any suggestions?
  • MPP LV2424 - USB Drivers?

    Just setup a MPP Solar LV2424 - and I'm loving it. The unit came with two cables, one an RS232 to serial port, and the 2nd a USB cable that goes from the USB out of the LV2424 to the USB in on a PC. Other's I see have acquired a serial port to USB adapter to connect the unit to the PC - I'd...
