PIP2424LV-MSX Charging Options
#1
So plan on using this for charging my 7s 24V 18650 lithium ion pack. So you have the option to setup user defined voltages and has 3 charge/voltage options.

Bulk Charging Voltage (C.V voltage)
Floating Charging voltage
Low DC Cut-off voltage

So for the bulk charging do I set it to 3.8-3.9 times 7 or 26.6V or 27.3 and then set the float voltage at 4V or 28V? So the pack is charged to 4V?

What's the recommended Low voltage DC cutoff, I know you can go down as low as 3V, but is 3.1-3.2V better?

Going that low is useless I stop mine at 3.4 v there is almost no energy difference between 3.4 & 2.9v you just hurting your cells for 1% more

It appears the CV mode is constant current then switches to constant voltage, so setting that to 28V should do the trick. I'll set the float voltage to 23.8V for now. I'm not sure I need that setting so I'll have to read when the charging cycle begins, etc.

I'll set the low voltage cutoff at 23.8V as well for the 3.4V you mentioned.

In this video are all the settings I run at the moment, they do change from time to time but.

Note mine 48v now.

I know this is an old thread, but do any of you PIP2424LV users have this issue where if the power usage is over 800W that it doesn't go from Grid to Battery? My PIP has been running great for almost a year now but it always has around 150-400W typical usage. This winter however I introduced a mini-split that takes up to 800W. This last few days has been cold and it's been running heat at around 800W 24/7 at the PIP. I noticed the other day it didn't switch back to Battery during the day once the solar brings the battery above the 26V threshold. The funny thing is as soon as I turn off the mini-split, and drop the usage down to around 200-300W then it suddenly goes to Battery. Is there a limit to where it doesn't allow the inverter to turn on unless it's set below some threshold?

How about you folks with the PIP4048s? Are there any issues with your PIPs going from Utility to Battery once the back to battery voltage has been reached?
