I wanted to be sure I set the device to the correct battery type. According to the manual - https://watts247.com/manuals/mpp/PIP-LV-MR/PIP-LV-MR 3K manual-20200428.pdf?x49702 it is set as a default to use AGM batteries.

From Will's video on the device I see he was using 2 SOK 12 volt Lithium batteries so I assumed they are to use. I purchased two SOK marine 12 volt/200amp hour batteries. https://www.sokbattery.com/products/sok-12v-206ah-lifepo4-battery

Do I need to set it to 'User Defined' (page 15, setting #5 in the manual) and then make explicit settings for settings #26 (Bulk charging voltage), #27 (Floating charging voltage) and #29 (Low DC cut-off voltage)

I see on the each of the 12 volt batteries it says the max charging voltage is 14.6 volts and max charging current is 50 amps.

Any help with the setting would be appreciated. Perhaps it's ok to just leave it as AGM? I noticed in the video that setting wasn't mentioned so perhaps it's not that important.

This is for a little houseboat I'm rebuilding. I'll ultimately have it on this boat wired to shore power for when I'm at a marina and I was planning on 2 of these panels as the max solar input says 750 Watts - https://store.santansolar.com/product/ht-solar-375w-72-cell-mono-solar-panel/

Any help will be appreciated!

I have that inverter and had to recently set it up. Here are the bulk and absorption values listed from Current Connected’s Charger & Inverter Section for SOK Batteries:

“Multiply voltages by 2 for 24v systems and by 4 for 48v systems
Charge Current (Per battery): 40a Preferred (50a Maximum)

Absorption Voltage: 14.6v preferred (14.4 Minimum)
Float Voltage: 13.8v preferred (13.6 Minimum)

Equalization: DISABLED

Low Voltage Disconnect (LVD): 11v

Equalization:
MUST BE DISABLED. SET DURATION TO 0 MINUTES.

If you can, we recommend setting the equalization voltage to 14.6v. With this set at 14.6, if an equalization is somehow triggered, you will not damage your battery.”

For your panels, the one you linked to should work as long as you only do two in parallel and not series. Here’s the numbers for those panels from page 7 of the user manual:

25A/9.36A(IMP)= 2.67, so two of those panels in parallel (9.36A*2 < 25A)

One panel VMP = 40.1V which is between
the recommended PV Array MPPT Voltage Range VMP of 30~ 50VDC

So two 375W panels in parallel would be: 40.1V * 18.72A = 750W = which is right at the max solar input capacity​

I hope this helps.
 
Thanks so much for this reply. I'll double check all my settings with it. It's all going in my hobo houseboat :)
 
No problem :) Definitely change it to user defined in setting 5 and plug those numbers in to settings 26, 27, & 29.

Good luck on the boat! I rebuilt one once myself, it’s a lot of work for sure.
