Thank you.

Found this informative article, note the table addressing what can be done with a two MPPT inverter, although not MPP Solar specific, I would say this article addresses all two MPPT input inverters. https://www.solarpowerworldonline.com/2014/02/dual-mppt-defined-understanding-mppt/

I am planning to install a system for the 120 volt usage in my house. Have a LV6548 inverter, have decided to go with SOK (probably 5) LiFeO4 batteries, and have found a good deal on Silfab 380 watt panels locally (supporting local economy, supporting American made, great specs). I wish to...

Tried to update firmware on both LV6548s. Computer tried to connect but connection was closed after each attempt as was unable to connect. I even tried changing each inverter from double phase to single phase then tried. No luck. Used the same cable that came with the SOK batteries to...

Thank you. I'll stick to the AiO inverters. The 2424 is currently online with upgrades to increase the panels as discussed, and adding two more LiFeSO4 batteries. The LV6548 still in the box waiting to be hooked up, but need the panels and the batteries, rack, etc. Hoping to make this...

Thanks for your response. Will do the 4s3P as you suggest. The AC I thought was 950 watts but when I look now I find 1150 watts. My pump pit is pulling 535 watts 24/7. I can shut down the waterfall pump at night if I have to. The freezer pulls 3.3 KWh a day.

Thank you for responding. I have a dumb question though, where does the 18A limit come in? I read that on the MPPTs of the 6548 each have a 60A limit. Is the 18 amp limit on the combiner box, and if so can a larger fuse be used safely?

Thank you timselectric, that is a relief and opens up more options for sure. The specs on the silfab is fantastic, but haven't seen them run over their panels with a tractor like Mission solar has and we get hail here in the spring, usually nickel to quarter size.

Thank you. Will check the rating for the SOK amps.

Thanks MichaelK, learning more as I wade deeper into solar. Didn't know exactly WHY I was reading and told by a friend to be sure the inverter is an MPPT, now I do.

Thank you for responding all. Timselectric, I too would like to overpanel as it seems with the current LV2424 I'm running for my koi pond set up with 10-200 watt I have yet to hit the 2000 watts they are supposed to put out so figure the new set up will no doubt fall short on power production...

Hello all. New to solar, started off with a solar kit which I assembled per their diagram but was never happy with it. It was an MPP Solar LV2424, 10-200 watt panels in two strings of 5 paralleled, two LiFePO4 batteries. It would revert to utility, usually on hot days but not always. So decided...

Had two MPPT 6548 solar inverters which I am replacing with a Sol-Ark 15K, while skimming through the manual it states if you are hooking up more than 2-3 batteries, they must be run through a busbar before the inverter. The SOK rack has 5 SOK batteries (no busbar) and just have them hooked up...

I have purchased the LV6548 but haven't hooked it up yet. What are the recommended settings for 26, 27 and 29? I have the 12v 200Ah LiFeSO4 Rich Solar batteries I will be hooking up to this unit, no communication capability with them that I am aware. Will be using the USE setting in...

This has been a learning experience for sure. Figure I'll buy 4 more of the RS panels which will give me enough to have two strings of 8 run in parallel for one of the MPPT inputs. Will get me close to max watts on one input allowing for winter cold temperatures and 20.8 amps, well below the...

I have an MPP Solar LV2424 inverter with two batteries, bought two more batteries about a month ago and they have been sitting in the solar shed waiting to be hooked up. I have read all batteries should be close to same voltage when connected. My plan is: 1. Charge each 12v battery with my...

Thanks for your response. Will do the 4s3P as you suggest. The AC I thought was 950 watts but when I look now I find 1150 watts. My pump pit is pulling 535 watts 24/7. I can shut down the waterfall pump at night if I have to. The freezer pulls 3.3 KWh a day.

Thank you. Seems 10 AWG is going to be the size I use, 8 is just turning out to be too much trouble and I've already bought a good set of crimpers that I can change dies, just can't seem to locate the size 8 for it.

I'm confused on figuring the amps. You take watts and divide by volts, correct? Is this total watts of the array divided by one strings volts? This would make the amperage 24.6 by my figures. (2400/97.2) Just trying to get a handle on this before moving onto the 6548. The midnite solar...

Thank you Danke. What is a Polaris type connection for the battery connection you mentioned? Don't recall reading about one before.

Will the MC4 connectors on 10 AWG connect with 8AWG, ie opposite pieces that would normally work together if same wire size. Thanks. Jacj

Thank you. Will have to rethink things now:unsure:

I've always had a charger that was basically plug and play (12v car batteries) I now have LiFO4 SOK batteries 48v and one of Dexters battery chargers but I have no idea what setting to put in for the volts and amps. Recommendations? Thank you,

I too have the MPP Solar LV2424, 10-200 watt panels and two LiFePSO4 200AH batteries, also purchased from shop solar kits. I am experiencing the same issues. I'm a newbie and in over my head at this point. Since I installed and fired up my system I've been having to run it in bypass mode in...

In some of the posts on here about the LV6548, a member had been in touch with MPP Solar and the rep said as long as was under 25 amp a person would be fine. The Rich Solar by my figures would be 20.4 amp, and the mission solar 345s I'm thinking of getting for the second SCC would be at 22amp...

Hello. First off, I have 10 200 watt panels, 2 strings of 5 each in parellel. 2-LiFeSo4 200AH batteries in series to make 24v. I have my output source set to SBU. I need input please on : 1. Voltage point back to utility source. 2. Voltage point back to battery mode. I think the...

On the 2424, it would drain the battery and go to utility, not using the panels for power or charge, sometimes air temp over 100*F, other days only 80*F. Sometimes I'd find it using utility, showing 107 v from panels, but not drawing any power from the panels, just from utility. As for my...

I feel your frustration. I too was very frustrated at first, feeling like I'd been left to figure it out for myself by the sellers. The so called support is in the form of 'EMAIL', in their case snail-mail. If it was someone depending on the system to power essential items and that was the...
