Hi, just adding some manuals on these batteries for easy access for forum members and related discussions. Main technical manual for their AGMs.

Sometimes people need a small load on / off switch breaker combo for DC systems. Blue sea offers some that are rated for 65 volt and some for 32 volt - even though they look very similar. Historically, he ones with white handles were rated for 65 volts, such as this 10 amp version and the...

Hi, I have a 5000 / 48 quattro for sale. It was used on my test bench to compare to some other inverters, chargers, and a honda 3000 generator. It ha not been used for any projects other than just some testing. I can sell it locally for pick up, or ship it within the continental US for...

Hi, I am looking for a good quality battery terminal cover for the battle born battery. I have some experience with their batteries, but was not completely happy with the terminal cover options that I could find. It could easily be that I just was tired when I was looking. The battery model...

Sometimes it is easier to show people things in photos than to describe them. So I made a little test fixture from left over parts, nothing fancy. In this case, some people asked about methods of dealing with pre-charging the capacitors on the input stage of inverters, and I had suggested that...

Hi - I am just collecting information here on this unit. Midnight solar kid marine solar charge controller. Not really trying to compare the features to other controllers on the market or pricing - just collecting info. I use some other controllers now for mobile projects and need some...

Hi, I was given a victron smart solar 100 / 50 that was not operational. One of the challenges of these units is that they cannot tolerate an accidental reverse battery polarity connection and this kills them off pretty fast. In this case it was accidentally reversed in a 12 volt system, so...

I have a one man off grid shop in Livermore, CA, near Livermore airport. This is on the East side of the SF Bay area. Historically I have specialized in helping people with their conversion van electrical systems and solar. Increasingly, I am involved with small back up power systems, such as...

Hi, my wife is on oxygen for a bit recovering from a procedure. She will be fine, so not a super big deal. So they sent us home with an oxygen generator and spare oxygen tanks as "backup" in case the grid power goes down or something else fails. This is all fine, but if I am out and the power...

Hi - just a quick intro. I live east of San Francisco and have a small van "electrical only" shop in Livermore. Also do some volunteer work with using similar equipment for disaster relief / grid down situations. Harry
