Thank you both. Will charge individually and then in series and check the cuttoff setting and change it. This was my first system, and it's for the koipond power. I have 12-200 watt Rich Solar panels and my power consumption runs about 800 watts except at night when the waterfall shuts down...

I have four 12v Rich solar batteries (LFePO) in series making a 48 volt battery for my LV6548. Last two mornings I go out and there is a fault and batteries are not charging and shows they are empty. Each battery checks out just a bit over 12v EXCEPT the last one that the positive terminal...

He's going for DC fans, do you just add up the watts each fan draws and make sure the panels make more than the watts needed and ignore the volts?

A friend has a greenhouse and wants to install multiple fans inside to move air, but doesn't want to use an inverter or batteries, just wants to power the fans directly off the solar panels so they run only during the day. My question is how to calculate the size of a panel array based on how...

Sun is out today and checked the leads from PV. Was getting 112v from the PV which are 2 strings of 5 panel series in parallel. I have tried both MPPT connectors on the 6548 and the inverter does not detect the panels. The only thing I can figure is there must be something in the settings...

Disconnected the PV cables from the inverter and checked voltage, it was only 26.6v, but it has been rainy today and cloudy so now that the settings have been changed to run single phase, once I get the volts up it should detect the PVs. From what I read in the manual, the voltage from the PVs...

Just checked the 6548 and sure enough, the setting was 2P2, so went in and changed it to SG1 and it started charging the batteries off utility and showed the inverter icon so know it's functioning in that aspect. Turned on the switch from the PV and nothing. That will definitely be this...

Thank you!!! I had COMPLETELY forgotten about the setting #28 for two phase. Will get that changed this weekend, as that's the soonest opportunity I'll have to tackle it again. I remember the frustration setting it up as I was slow at making the chages. I had also forgotten about the bonding.

I had this 6548 hooked up before and it worked (with communication issues), and double checked the wiring before putting the front panel with controller back on. I did precharge, don't have a regular resistor so I use a carpenters pencil as a resistor. Thank you for the link to the calculator...

Thank you for responding. The inverter panel does not show panels are connected, so it shows 0 volts from PV. Good to know I can run all 10 in series and not mess anything up. Have not been happy with this system, ie MPP solar and rich solar products.

Greetings. I had an LV2424 I was using on my koipond with 4 12v Rich Solar batteries configured for 24v and 10 200watt Rich Solar panels hooked up 5panels in string, 2 strings. This setup worked fine for the LV2424, but the 2424 stopped switching over to utility, and it would just drain the...

Believe me, I'd LOVE to. But gotta pay for the sol-ark first. I've already gone over budget :LOL:

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

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...

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...

I have two LV6548 inverters with 5 SOK rack batteries, used the pylon setting and after several days would get code 62. Would shut the inverters down and this would reset, but problem would reoccur several days later. Batteries SOC varied from one another, OVP tripped on the batteries, one had...

I think I understand now. So you are talking about equal length of cable in terms of each inverter, ie, total of inverter #1 is the same as total cable length of inverter #2. Am I correct? Also, thank you for the link to the book, this gives me some good info to read and understand more...

Here’s a crude sketch of what I’m looking at. I have the 3’ battery cables (2/O) going from the bus bar to inverters and the fuses. I need to purchase cable to go from the bus bar to the fuse box now. I see 9” is a standard length to purchase so this would be adding another 11” to the positive...

Have read the battery cable lengths must be the same on POS and NEG otherwise it effects the volts. I am installing two LV6548 inverters for two phase, all battery lengths equal but I forgot to account for a fuse (125 amp) in the POS cable from buss bar to inverter which is approx. 4" long and...

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

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,

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

So I will be using the electric companies grounding system on my entire system. I was hoping to use my own earth ground, and only use the electric companies load lines and neutral. So the only way to get around this is not to have utility hooked up to the inverters for back up?

I have most of my supplies and planning my install of two LV6548 inverters to power my house. But am a bit confused on the grounding line coming from utility. For utility power IN on the two 6548s, do I use the utility ground, or my own earth ground I will be using on the AC power OUT to my...

Thank you.

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

oh. 48v.

Hadn't thought of looking there. I don't have Facebook but my wife does. I went and checked it out briefly and it's definitely worth looking through.

Around 240 volts I'm figuring. It all depends on what panels I can buy come Monday. Going down to OK City to purchase and bring back. Had figured on the Silfab 380, but later when I called to see what other items they carried, they'd run out of the S 380s so figured I'd wait till closer to...

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.

Being 150' distance from array to inverter, pulling the PV wire bundle (two runs, so 4 wires) will be difficult enough without the ends on and I would think impossible with ends. Direct burial would save money as PVC conduit has become unreal as all PVC products have, but hesitant to go that...

I will be installing my solar array 150' from the inverter and decided to go with 8awg wire, when looking for connectors to fit, it has turned out to be challenging. I purchased this crimper with dies for regular 10 and 12 awg connectors...

Thank you for your response. For the AC going out from the two LV6548s will just use a small two leg breaker box then before the lines head to the main panel in the house. My PV lines coming in will be connected to a DC disconnect switch before the inverters so I should be good. No codes here...

I have a question. In response #5 from MichaelK he talks about a breaker box after the inverter and that his line goes straight to his main panel. What are the main reasons for having a breaker box right after the inverter since it’s going to the houses main breaker panel, and will an average...

My original plan was to use one LV6548 to power my 120v needs in my house, but want to use the existing breaker panel box so I've decided to purchase another LV6548 so I can run two power legs to the box to simplify my install. I plan on installing a small breaker box and have it connected to...
