Nice to not have to run wires through the though more expensive than the chinese one with a wired meter. Seems like victron will integrate directly into the app. this is what I was thinking but hearing confirmation is so helpful.ĭo you also have & recommend a shunt be added? I have seen the threds about the cheaper one as well as Victron. At I know he and Nigel are friends.Wow, thanks for clarifying. (Been wondering about take on the website name. There is another website, that offers a course on boat electrics, there is a fee for that course. Also read the articles on alternators to better understand your alternator and its strengths and limitations.

Read the article on MarineHowTo on the 1-2-B battery switch and how to use it. There is a bit more to this than simply sticking another cable on the battery. You are correct if the alternator output by passes the switch then turning the switch off won't crash the alternator. Essentially it only connects the two batteries when there is a charging voltage present, when a charge voltage isn't present on either side, then the relay opens and the batteries are disconnected. Maine Sails article on the ACR explains the system much more clearly than I can. I'm not familiar with the Victron Argo, so I can't comment specifically. The Victron has been passed on to a deserving soul. The original Smart Gauge is now used to monitor the start battery.

Amps in/out, SOC, SOH (state of Health) Voltage, and it calculates the time required to be fully charged based on the current amp input.

This year I added a Balmar SG200 with the smart shunt and bluetooth dongle. Added a Victron 704, great device told me amps in/out, watts, voltage, but the SOC function was a pain. I'm on my third Battery Monitor, started with the Balmar SmartGuage, worked well, but didn't tell me about the amps in/amps out. Please correct anything you see that I’m doing that’ll bite me in the rearend later. For the starter, I Then I have to figure out which route to take with it on its way to the starting battery. My plan is to run a cable directly from the alternator (I’ve been told that’ll save it if my kids turn the switch off while we are out) to the house bank with a fuse at the battery. I have a M25-xp with a 51 amp alternator jumped to the starter. If an ACR is better for that then I’m all for it. My reasoning for going with an Isolator at all was because I was trying to make sure current didn't flow from my start battery to fill the house, and protect current from going back to the alternator. The Isolator I got was the Victron Argofet 3 bank isolator because it doesn’t have voltage drop like others. I am not against returning it and getting something else.

I understand what you’re saying about the monitor. The fact that I’ve probably been given bad advice is spot on, and even good advice I’m sure I misremembered.

If this information is entered inaccurately, the SOC will not be accurate. Victron has a good reputation for accuracy, but it does require programming with an accurate measure of battery capacity and the Peukert number for the battery. In terms of accuracy and ease of use, the Balmar SG 200 is far in the lead. Respected brands include Victron and Balmar. Blue Sea is an outstanding company to do business with, their products are top notch and they have lifetime no hassle warrantees.īattery monitors also come in different flavors, some are better than others in accuracy and ease of use. There will be no voltage loss across this relay. A better way is to use a relay based isolator, like the Blue Sea ACR (Automatic Charging Relay). This will lead to shorter battery life because the batteries will not be properly charged causing them to sulfate more quickly. The Renogy Isolator you have has a serious limitation in that it will induce a voltage drop when the batteries are being charged. See the article on on ACRs, automatic charging relays. This often leads to under charging the house bank.

When alternator output is directed to the starter first the battery that was used to start the engine will be charged first and reach full capacity quickly as very little energy is used to start the motor, something around 1 ah or less. It is not necessarily the best way for battery charging, especially if the house and start batteries are separate as they appear to be in your schematic. This is done for expediency during installation, lower cost of installation, and fewer warranty claims. If you haven't yet visit to read the excellent articles on batteries, charging, monitoring, and isolating among others you should before you go any further or spend any more money.įactory wired alternators are typically tied to the starter.
