What happens when I have multiple charge sources charging a single battery bank? I get this question asked almost every day. "I have a battery charger, an alternator, and solar panels charging the same battery. Does it get overcharged?" Here are some thoughts on the subject.....

This is the story of the final installation of Victron equipment on this off-grid solar house, this house has a twist though, it is made of straw bales......

I'm getting weird reading from my Victron BMV amp hour meter. The readings don't seem to relate to what I think is happening. HELP !

Its a total No-No to connect AC Neutral to Ground on board a boat.  One boat did by accident, see what happened.......

We all know that electricity and water don't mix.  What we may not be aware of is how many drownings occur every year because of electrical current in the water.  The new ABYC standard requiring ELCI circuit breakers on shore power service to boats is an attempt to reduce the amount of stray electrical current in the water - read below for an explanation of what this is all about.

This is just a small sub-panel on this French built saiboat. Part of the panel is 12 volt and part is 24 volt

A Bluetooth dongle is now available so that you can read data from your Victron Energy BMV energy Monitor or MPPT Solar Charge Controller on an iPhone, iPad or Android Devices

I am always referring to these tables so I thought I would put them in my blog where they will be easier to find

This post gives a few pointers for sizing wire in AC Circuits

ANL and MEGA fuses are similar high amperage DC fuses but there are some big differences. Here is a comparison.....

I end up looking up this table so often I decided to post it on my blog

This was my first time installing one of the Balmar Serpentine kits and I was a bit apprehensive. Although I had read the instructions several times it still isn't quite the same as actually doing it. Read how it all turned out.........

What are the factors that go in to deciding how big a battery charger to install on a sailboat?

The start isolation feature of Blue Sea Systems ACR's is even incorporated into the name of the device. It is an optional feature with a very specific application......

Victron Energy more than doubles its warranty period, now five years for all products except batteries

Question: I need to replace my alternator for a Yanmar 3YM30 /2006. It is a Hitachi 60amp and I am thinking in replacing it with a higher amp output. I might then need to replace perhaps the pulleys for the water pump and the crank shaft and then of course consider a serpentine or other type of belts. Would appreciate your suggestions?. Thanks.

A discussion on the relative merits of transformers and galvanic isolators

There are many ways to do a battery layout for multi-engine boats, here is one simple layout using remote switches.

What does an alternator regulator do and how does it work? An alternator regulator supplies current to the rotating part of the alternator. The rotating part is called the rotor, and when current is applied to it it becomes an electromagnet. Its rotation generates an alternating current in the fixed windings of the alternator, called the stator. The regulator acts as a control mechanism for this process

This small sailboat got a custom 360 Panel from Blue Sea Systems that was required to incorporate an existing Blue Sea Systems digital meter and another brand digital meter

Help!  My Batteries are getting hot!  What should I do?
