Balmar Max Charge MC-614 voltage regulator.

In addition to MasterVolt products, I also installed: IвЂ™m sure I didnвЂ™t do everything as perfectly as an ABYC certified installer, but I learned a lot about the system, and I feel it is far safer than the previous install. I had considered this, but knowing the markup that both the labor and parts get, I decided to use my pretty extensive electrical knowledge and do it myself to save money, and also to know it inside and out in case anything ever happened.

I chose to do the design and install myself, when many would opt to pay a specialist. The design of this system took me multiple months, and required ordering additional parts after initial install once I found limitations.

The system consists of the following MasterVolt components Overview diagram of GraceвЂ™s MasterVolt power system MasterVolt provides methods of doing this with a more integrated system using a network called MasterBus. On Jammy I used MasterVolt only for charging, and did most of my monitoring via Maretron NMEA 2000 devices ( seen in the network diagram here) which were expensive, required somewhat complex installs, and were mostly independent. I chose to modify this as well, as I did not intend on having a standalone starting battery given the weight and space it would use.ДЄfter a lot of investigation, I chose to use MasterVolt as the core of the system responsible for charging, inverting, monitoring and distribution. The default factory battery switches allowed you to have one battery on, or both batteries in parallel for starting or other operations. They were starting-class batteries as well, which are not necessarily the greatest choice for a house battery load. The worst part was the two non marine-class starting batteries that powered everything вЂ“ a total of about 140 amp hours if they were brand new, which they werenвЂ™t.

GraceвЂ™s existing system consisted of a very basic battery charger that I knew would not keep up with my needs.

#NMEA 2000 NETWORK SHUNT UPGRADE#

This is the first in a series of posts on my power system upgrade which will cover design, install, and specific implementation challenges. I chose to use MasterVolt as the primary charging, distribution and control system, Balmar for engine power management, and Firefly carbon foam batteries as the heart. Having completely redone the power system on Jammy, and wanting to have all the comforts of home, it was important to make sure the new system was well thought out and reliable. For 4-20mA sensors, you will need to add a 250 ohms, 1% tolerance resistor and then create a calibration table with two points, 1 and 5 volts that will correspond with the maximum and minimum values of the sensor.Grace came with a very basic power system which had some major problems.You can also connect to the W connection of the alternator as described in the Alba-Combi Manual. If this is the case, as an alternative, you can often connect to the Ignition Coil of a gas engine. For example, if the RPM sensor is reading the teeth of the flywheel and say we have 120 teeth and the max rpm is 4000 rpm, that will equate to 120 pulses-rpm * (4000rpm/60sec) = 8000 pulses-per-revolution or 8000hz, this will not be compatible with the Alba-Combi for RPM sensing. This equates to about 60 pulses per revolution at 4000 rpm, anything higher than that will not be compatible. For RPM the Alba-Combi can handle a maximum input signal of 4000hz.PGN 130316 вЂ“В Temperature, Extended RangeДimensions: 105 x 86 x 59 mm (DIN 43880 size 6).PGN 127493 вЂ“В Transmission Parameters, Dynamic.PGN 127489 вЂ“В Engine Parameters, Dynamic.
