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...
