I have a recently installed solar system that consists of the following. Sol-Ark 15K - Grid tied 8.2 KW of SunPower panels on a ground mount I am in the process of trying to decide on how to move forward with adding batteries and a generator to the system. The primary reason we are wanting the...

Very cool. My car is stock suspension only in so far as the style and rough mounting points. The car is a 25.2 cage/chassis certification and has been 7.30's @ 195-196 mph in the 1/4 (4.70's @ 155-156 mph in the 1/8th). The car is a 1986 Mercury Capri (like a foxbody Mustang). What did your car...

The Honda eu7000is has the ability to use a twobwire start kit which will allow it to be turned on and off by the inverter.

Thank you for the response. I have not tried using a meter yet, though I have a Kill-A-Watt plugged in where I can see it from the kitchen table. I have never seen it move more than from 60.0 to 59.9 or 60.1. That seems to apply to when the inverter has solar to operate or at night when the grid...

During the non air conditioning seasons (provided we get decent sun) my batteries are discharged (per the closed loop BMS) to about 71-73% when the sun starts charging us up. On a normal day the batteries are charged by noon or shortly after and we start selling to the grid. In your opinion how...

Hello everyone. My wife and I are having solar installed next month (after a lengthy fight to get what I want from the vendor). The system is as follows. 8.2 KW ground mount 20- 420 watt Sunpower panels Sol-Ark 15K inverter - grid tied The only battery option the installer will use is the...

You did some drag racing? What type/class?

I have a Sol-ark 15k inverter and eight SOK batteries. I would like to add a generator to the system. I have a Honda Eu700is (probably just laege enough) but, the property has a natural gas well so I am leaning towards a small standby generator. Does anyone have any feedback on one brand versus...

A few of them. Lots of reading about peoples systems more so than a more to the point review of people dealing with the vendors (unless I missed a something).

We live near Paola. I have looked at Homegrid a little and Fortress Power. I have spent a little time around the Joplin area. We used to race down at MOKAN back in the day.

Does holding the batteries that high pose any danger to the cells (I am asking out of ignorance)? When the communications were on the bank would come up to 57.1-57.2V and then ramp down to 56.4V and then back up to 56.9V throughout the afternoon. I'm still kind of at a loss as to how the...

Do you have any advice on who's kit to use? When using a natural gas kit can the generator be started remotely by Sol-ark? The generator I have only has something like four hours on it so I wouldn't mind using it. My other concern with the Honda is it only being 5500 running watts. This wouldn't...

Guys, thank you for the responses. Not the answers I was hoping for, but oh well. The frustrating part is the company that installed the system didn't answer any of these questions when I originally asked them and (at least on the grid connection after failure) Sol-ark (not the solar engineering...

I was not aware of that. I will have to give him another call.

I currently have a Honda EU7000is and it is my first choice. I was considering the smallest Champion home standby generator (which is why I was trying to speak with Scott at Practical Preppers) as an option as we have a natural gas well on the property.

Hello, Hoping to gain a better understanding of how a solar array will perform in cold vs hot weather. My system was installed at the first of this year and consists of a Sol-ark 15K with 8200 watts of Sunpower panels (20- 410 watt panels, aimed south, and set at 30* I believe) installed on a...

I am waiting for a call back from the installer currently. I am not/have not been super impressed with them so far, so I'm not overly optimistic. We have been having this issue occur two to three times a week (only when the solar is functioning) under pretty much any range of conditions. For...

Cool. I have a stock suspension 28x10.5 tire or 275 drag radial car.

Thank you for replying. Just to make sure I am understanding things correctly. As configured without batteries there is no way to see the houses composite usage versus generation for the full day. If batteries are added the system will remain active 24 hours a day and log the information for all...

Thank you for the response. Where would I find the temperature power coefficient data? I have called Sunpower trying to get that data three different times and come away with nothing other than being frustrated.

I am in the process of adding a server rack type of battery bank (probably SOK) and a generator to my existing grid tied system (Sol-Ark 15K and 8.2 KW of Sunpower panels on a ground mount). Due to the location of the two breaker boxes in the finish basement the inverter had to be placed on the...

DIYrich Catching the batteries during a time frame like you described the cells are not as well balanced. These numbers are from 2/14 @ 5:09 p.m. Pack 1- high- C5- 3558 mV Low- C7- 3348 mV Pack 2- high- C5- 3668 mV Low- C10- 3501 mV Pack 3- high- C13- 3656 mV...

What constitutes being "way out of balance " and when is the correct time to look at cells to determine this? I have been taking readings of all the different battery info, but I don't really know what they mean.

To that point. Last night my #3 was showing a high cell reading at 3320mV and lowest cell at 3312 mV (@ 84.13% SOC at reading and ended the charging cycle @ 98.55%) while #4 (the pack reaching the lowest SOC @ 79.65% at reading and ended the charge cycle 90.76 % was showing high @ 3317 mV and...

Mine is 360" SBF with twin 76mm turbos. Prior to that it was the same motor (different cam) with a reverse rotation Procharger F2R.

Sorry. I should have been more clear. The cell voltages I listed were during discharge. The cells on #4 were highest 3558 mV and 3523 mV lowest. While #1's (highest SOC) highest cell @ 3640 mV and lowest @ 3377 mV.

Lt.Dan, What type of inverter do you have? My 15K does not appear to have the ability to set different stages to the charging process (I have float, absorption, and equalization- which Sol-ark said not to use on LFP). Ultimately what I would like is to figure out how to get the inverter and the...

I have eight SOK 48V batteries (two racks of four batteries 1-4 and 5-8 with one set of cables per bank to the inverter. All cables are identicalin length) connected with communications to Sol-ark 15K. The batteries have been in service six months at this point. Starting 02/07 the report SOC on...
