I was surprised especially since the batteries that are in there are much smaller than a standard car battery, only taking about 2/3 of the battery tray width. So I would have expected some sag on startup, but who knows? As I mentioned, I saw a video recently where the presenter mentioned brand...

Thanks for the pertinent page of the manual. As I mentioned, I did that test and it peaked at 5mV and rolled back to about 2 mV after a few moments. Those must be some super-duper low internal resistance batteries, because I watched one other video last week where the presenter mentioned he...

A few days earlier I did put a meter across the alternator terminals as instructed, and read 26.5 volts with engine running. I just want to be sure the unit is 100% working the way intended. Does anyone know how many millivolts it takes to deflect the meter full scale?

I did a few tests today: Placed a voltmeter across the battery meter terminals and started the generator. It read -5mV then ramped down to -3mV. Then I did the removal of FU1. With it removed, the needle moved less than 1mm into the red, about a needle thickness. With the fuse installed, it...

Guys, thank you for all the advice on the fuel tanks. I am thinking that 55 gallons should be enough, but I want a tank that the oil delivery guys will not have a problem with filling. That said, I've watched many MEP803A startup videos and in every one of them the battery meter moves to the...

I take advantage of the fact that a solar panel is a current source and will maintain a certain amount of current throughout the day. By placing it in a location where it gets no direct sun, I limit the current to less than half an amp. That is enough to counteract the internal discharge current...

I got my $60 cable/connector today, and made up my interface to MC4 connectors. I incorporated a 150A diode in it to prevent reverse current flow at night. The panel will sit out of direct sun, so it will produce about an amp of charge current to keep the starting battery topped off. Will hook...

From what I can tell reading the label, it appears I need only 0.1oz of biocide per 10 gallons of diesel. Stuff's expensive, but when you realize one bottle treats almost 2000 gallons, that's pretty good. I'm on the lookout for either a good clean 55 gallon drum, or a used oil tank for this.

What do you recommend for a biocide? I'm building a shopping list.

Would that be this stuff here?

Looks like DF2 and several others listed here; DF2 = #2 heating oil?

Those tanks must be hard to find and expensive! I wonder how #2 heating oil works in this genset? That's what I plan to run. My 2000 gallon main tank for heating has probably got some oil in there from 20 years ago, as I top off the tank every other year, so I never use up all the old oil, it...

Since I use home heating oil number two fuel oil I am wondering if this is pretty much ideal to run the generator on? I run it in my excavator and I have no issues with the engine running on that. So would it be the same for the MEP 803a?

Yes I am aware of the auxiliary fuel input and I actually tested it with a 5 gallon container and ran the auxiliary pump and got the last gallon out of the tank. So what I'm interested in knowing is where I can get a recommended auxiliary fuel tank that's low profile and safe to store next to...

I got a temporary ground hooked up to the generator trailer now. (Still waiting for the crane to come and lift cab off excavator so I can get that repaired and use it to move this to a slab permanent installation). Was cloudy all day and the air conditioning prevented battery charging with weak...

My second EG4 Chargeverter arrived today. The company originally had the older yellow version listed as in stock. When I ordered, it said out of stock, so I e-mailed them and they said they have a few scratch and dent units left and they'd sell to me for a 20% discount. So I bought the new one...

I have spare solar panels laying around and use them as battery tenders, such as on my pickup, which will kill a battery stone dead in just a week of sitting. My plan is to set one up and connect to the slave port. It may not be elegant, but it will offset any phantom load that may be on the...

A nearby lightning strike or any big static discharge will generate an EMP. Devices within a certain radius will be affected or even damaged. The solar panels were isolated by the charge controller and 80' of underground wiring from panels to charge controller. However, items NOT connected to...

I've been shopping around for a slave connector, as I plan to use it with a solar panel to create a battery tender/trickle charger. Some of the connectors go as high as $199. I found this one at about $60, but it still seems high. Are there any less expensive sources for this connector?

The only time I would remove a panel is for an upgrade. So the grounds will be continuous. All panels have to be present for the series connection to carry current. Those lightning stories are downright crazy. I'd heard such stories of "it was just overcast, then the dog got hit by a bolt of...
