  • Post in thread: 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...

  • Post in thread: 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...
  • Post in thread: 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?
  • Post in thread: 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?

    dessmonitor.com doesn't resolve to an actual website. is there a different spelling?
  • Post in thread: Solar Combiner boxes - (they in Parallel or Series)

    newbie question I'm having trouble locating answers to Do solar combiner boxes wire the panels in Series or Parallel, or is it configurable?
  • Post in thread: 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?
  • Post in thread: Every night at 11pm my Grid wattage spikes

    I thought that might be possible, so a few days ago I set the battery to only charge from Solar for now to eliminate that as a potential. Still, at 11pm grid jumps up 125w like clock work. Battery settings - edit Battery type User Charger source priority Solar only Shutdown battery voltage 21.6...
  • Post in thread: 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...

    sorry, not sure what the OSO setting is?
  • Post in thread: 12v200ah vs 24v100ah?

    I need ~ 10kWh of battery storage. (4 batteries of either 12v200ah or 4 24v100ah) the kWh is the same between a 12v200ah and a 24v100ah, but the 12v batteries are about $130 less. Is there a reason (aside from having to series connect a few extra in the 12v scenario) for picking the 24v...

    Hey Dan - wanted to follow-up. It was the powersave option. Disabled it, and there is no more 120v cycling output. Thank you again!

    I had also placed an order, the 280ah cells arrived within about 8 days I believe. EVE cells, with screw in studs.

    Thanks Dan I’ll check that next visit.
  • Post in thread: MPP LV2424 - USB Drivers?

    Thanks - I ended up getting an rs232 to USB adapter, and WatchPower works with it. I just wish I could've used the existing USB cable provided without the adapter.
  • Post in thread: Every night at 11pm my Grid wattage spikes

    ah, thanks. As I'm monitoring remotely via SolarAssistant I had to find that setting in SA and yes, it's locked down as Solar only
