I’ve got one for you. Inverter wouldn’t turn on with remote switch so tried a little trouble shooting and could get the inverter to come on manually after a few repeats of pushing the power button and there’s a fuseable link wired to the inverter from the batteries. When I can’t get the inverter to come on I test and can get 12 volts on the battery side of the fuse and 12 volts on the inverter side of the fuse. It when the inverter doesn’t want to power on I’ll test the fuse again and it will test 12 volts on the battery side of the fuse but 3 or 4 volts on the inverter side. Tried a new fuse and getting the same results.
Jeff, you just answered so many burning questions (fortunately I mean that in the figurative sense) I had about my first-ever boat with an inverter system. Thanks!
Sounds like Marcus would benefit from one of the newer inverter/chargers that has the ability to invert in sync with the incoming AC power and “boost” it to at least handle temporary overloads. Perhaps you could talk about this kind of device in a future episode?
Great stuff! Here's one that is a head scratcher for me.. After years of running properly. My inverter is tripping when the port engine is running at more than 1500 RPMs (2001 4788 w 370's) . I'm assuming that alternator is charging the the house bank and the inverter is 'inverting' from those batteries.. Heard of that before? And where to start Alternator, Batteries or Inverter?
Interesting topic Jeff, thank you for sharing it! There is a question popping up in my mind I want ask you. Kids from our boat club have installed on sailboat Renogy 200ah Lithium battery and Renogy 2000W/ 240V inverter and asked me if this inverter is safe device… Well I’ve went true the manual few times and it looks like this inverter have quite interesting function. When is connected to shore power is putting the inverter part on standby and same time is jumping AC power to the outlets. As well when shore power is off is switching to inverter. Some kind of ups function. My biggest concern about this unknown brand for me is that might not have grounding protection. In case the heater in the coffee machine get shorted to ground then 240V can get to the lithium battery true the grounding> common negative. I was about to connect 300mV grounding tester but I wasn’t sure if there is an issue how the lithium battery will react. Soo before making experiments I think is good idea to get more information. Renogy customer service haven’t replied back. So here I am with my long question. Do you have any experience with this brand Renogy and what would you recommend to check/ test? Appreciate your time and thank you in advance!
Not familar with either Renogy products, albeit familiar with Renogy in name only. Installing an inverter and a battery system a boat, as you imply, is more involved then simply connecting one to another. When installing an AC system, one should take into consideration the grounding implications and also associated circuit breakers. Same goes with a battery, in most cases the battery needs to be tied to DC ground.
I really appreciate this video, as this connection is what I’m currently installing on my boat. Can you shed light on if this is correct: Inverter power and fuse protection: DC (house battery) to fuse, to a T fuse, to a ON/OFF switch to positive Dc power Inverter. OR am I suppose to go House battery to fuse to On/OFF switch to T fuse to inverter? Thanks so much! Keep up the amazing information! I’d be so lost without your guidance on my first boat/re-wire.
Disregard: I re looked through my notes and found: inverter: to T FUSE, to switch, to another fuse before battery. I do recall a episode where you stated (T fuse as close to inverter as possible)
Hi Jeff, Thank you for donating your time to help us boaters. I’m Rod and am the proud owner of a Swan 44 MKII. Recently, I began experiencing the following issue: when on shore power and I run either the microwave oven or a shop vac, the unit runs for one second and shuts down. It appears the inverter / charger resets because after it trips it comes back on line. Note the inverter switch is off when I’m on shore power. I’m able to use my AC outlets to charge phones and other devices that do not draw a lot of amps with no issue. My workaround has been to shout off shore power and turn on the inverter which allows the microwave or shop vac to run just fine. This is a new problem. Previously I was able to run the microwave, shop vac or anything else while on shore power. Do you have any thoughts on what could be causing the issue and a solution. Also, my electronics are all original and are 21 years old. I have the build sheet from the factory which provides an inventory of all of the electronics. I’d would like to upgrade and modernize the electronics and systems and do not know where to start. Is this a project your company can take on? IZZI is based in Sausalito, CA. Thank you, Rod
Hi Rod, thanks for your feedback, sounds like you might have a bad connection to shorepower. You can eliminate any electrical item that is common to inverter, as your issue doesn't occur with the inverter. Probably shore power inlet is a likely culprit, remove and inspect the shore power inlet. Also, inspect the double AC main breaker.
Hi Jeff. I have a Xantrex charger inverter. The manual says I have to have a breaker on the ac side of unit which is in a van build. Others have told me it's not necessary because the shore power hook up breaker is enough. They say a special unit, not the simple plugin type is better because it tells you all kinds of info about that 30 amp hook up on the post. What is your opinion? I have noticed that you use a lot of Xantrex in your vids. Thanks..
Hi Robert, you definitely want to have a circuit protection to the AC input feed of the inverter. This breaker should be sized to handle the max amperage of the inverter/charger and also the AC wire size. In most installs, the AC breaker for the inverter/charger is separate then the AC main breaker for the vessel.
So even with shore power or generator power, if your inverter charger fails those circuits are dead without any way to power them? Assuming you are wired as described in this video.
Hello JEFF & PYS!: SUBJECT: What happens to your boat's inverter/charger WHEN the shore power source, 50Amp, L1 & L2 HOT leads are NOT 180 degrees 'Out of Phase'? AS an RV/Boat dealer shop electrician, this issue has come up. Many boaters also have large RV's that use 50Amp, separate HOT L1 and HOT L2 Shore Power. BUT, in the USA, (with few exceptions), most boats and RV's DO NOT have any 240V appliances onboard. Question 1: What percentage of boats you work on, have 240V appliances?? Question 2: Do you ever find marinas where 50Amp shore power L1 & L2 are NOT 180 degrees OUT OF PHASE? Question 3: If answer to Q2 is a yes, what happens to the inverter/charger if L1/L2 are not 180 out of phase???? SPECIAL NOTE: Most fancy 50A shore power cord power condition status checking 'add-on'/plug-in devices DO NOT TEST for L1/L2's 180 opposed phase relationship status. Most 50A, add-on, plug-in, shore power cord devices only test for: 1. L1 & L2 voltage level status with respect to NEUTRAL wire. 2. Ground lead's impedance status (if it's a high $$$$ unit). 3. L1 & L2's R.C. Residual Current loss status, i.e. GFCI; but NOT L1/L2's proper 180 degree OUT-OF-PHASE relationship status'. Thank you.
Hey Jeff why does my panel make a high frequency noise when I switch on the cabin light circuit? I recently replaced the bulbs to led from incandescent. By the way this noise my wife can hear but I cannot. Must have been the loud music when I was much younger.
Why is the inverter on invert when on shore power? If Shore power goes off, then my my batteries supply power to loads. An extended power loss will drain the batteries if I'm not on the boat. I have a 82 Roughwater and a 2000w charger/inverter. I have a battery monitor with an an inverter and a charger switch. Also a 12v switch on main panel. The only time I have inverter on invert is when cruising. Is this normal? It works but is it proper? Owned the boat 17 yrs.Thanks for all your info
Hi Jim, you bring a good point. Some boaters choose to enable their inverters, even when connected to shore power. If shore power is lost, then the inverter runs the AC loads from the batteries. Depending on the AC loads, the battery bank will run for a few hours or a few days, and eventually the battery bank will be empty powering the AC loads via the inverter. My advice is to only enable the inverter, when a boater is intentionally wanting to run AC loads from an inverter, otherwise you might inadvertently discharge your house batteries/.
Great video, and it comes at a very opportune time for me. I have been trying to figure out another aspect of the Inverter/Charger--why not having a separate neutral bus for the Inverter output will trip the shore power GFI. I understand the ground/neutral bond is (in inverter mode) switched so that the output neutral and ground are connected, but when the shore power is plugged in that connection is terminated. Does the GFI trip due to lag in the switch?
Just found the answer in one of the articles on your website --www.pysystems.ca/resources/articles/elci-breaker-with-an-inverter-charger/ Thanks again for all the great info!
Hi Al, not sure i understood your question, but here goes: when installing an inverter/charger, and when a portion of the AC loads are non-inverter loads and inverter loads, the inverter loads need to have a separate AC neutral bus dedicated to loads powered by the inverter. Failing to do so, will cause the shore GFCI or ELCI to trip.
@@PacificYachtSystems Sorry I wasn't as clear as I could have been. I understand that it's the ground/neutral connection at the inverter output that causes the fault. I just couldn't figure out why that connection would be closed when in AC mode. This article, that I found on your website, -www.pysystems.ca/resources/articles/elci-breaker-with-an-inverter-charger/ explains, as I suspected, that the trip happens in the time it takes to switch over from Inverter to Flow through mode. So I'm good for now. Thanks again. I've learned a tremendous amount from your videos and now I've discovered the website too!
Running from the inverter itself yes you would need a bigger inverter to run more loads. As long as the battery bank and wiring is big enough. From shore, An inverter with assist mode like the Victrons will add the inverter power to the shore power to allow you to run more from the dock. But it really depends how it's wired up. A 30a shore power cord can already run 2 large appliances as is.
If your inverter is an inverter/charger, then yes, because you want your charger to pe powered by AC when connected to shore power. If you have an inverter only, then the battery switch can be turned off, or you can disable the inverter function on the inverter itself or at the inverter remote.
Hi Jeff, thanks for all the videos! What is your opinion on having a portable inverter/lithium battery such as the Ecoflow delta as opposed to increasing the house battery bank and installing an inverter. Are there any safety risks with such an ungrounded portable device outputting such high voltage?
Hmmm, no experience with such a product. As a point of reference, haven't seen anything like this in our service area. Anyone else have experience with this Ecoflow Delta product?
@@PacificYachtSystems I bought a 1500 Wh "solar generator" which is a weird name (at least to me) for a lithium battery packaged together with an inverter. It weighs 40 pounds and is 14' tall, 14' deep and 6' wide. On my new-to-me boat I have brought it along on overnights as backup to charge the never ending devices everyone brings with them. Means I can leave my inverter off and save the house bank for the fridge etc. I have 200 amp hours of gel (100 usable) and this adds another 100 usable amp hours. It is an easy way to extend my useable power for short trips and when I get to that part of the never ending project list where I add solar and lithium and a new inverter (and a charge isolator. and a smart switch. and rewire the mess of a panel. and and and...) to my boat I won't need it but it is handy for now, and also nice for camping and around home.
