Can I leave my boat motor on to keep my battery charged while drawing substantially from the inverter or will this damage my motors marine alternator?

I have not used mine with motor running as of yet,I have it in a Rv and used breathing machine ( c-pap) and also had a 20" box fan running @ same time,when first turned on it said it had 12.68 volts,ran both all nite (7 hrs) and when I looked before shuting off it said 12.06 volts so it didn't draw to much.....I have a 200hp O/B and it only has a 35amp alt so they don't put out much amperage,,,,,,,

Yes. I separated my batteries for one to crank the motor and one to run house accessories. When the motor starts, the cranking battery gets charged first, then when 13.2 volts or so are reached the relay turns on and charges the house battery. At this point both batteries are being charged at the same time. My boat has a 70amp alt on it and the system works great. Pain to install but well worth it. Hope this helps. ~ Robert

Absolutely nothing. That is if your boat has a battery in it. Great piece of equipment.

your power leads from the battery are reversed! a dc motor like whats in the boat will run forward or reverse by simply changing the polarity of the leads!

I would think it would charge it no problem. I would leave it in maintenance mode or automatic mode, to prevent damage to the battery .. the chargers do a good job deciding what mode works best depending on the battery voltage. I have mine running to marine 12 volts and two 6 volts hooked in series. When they are pretty much drained it will take around an hour to bring them back. What i like is if I'm using a lot of power it will adjust its output automatically..

I would have to know all about your electrical system to answer that question, (battery amp hours, equipment draw, hours the equipment will be used, how often your main engine alternator would run, alternator output, etc. etc.) unless your boat has room for many large panels, you will not be able to recharge you battery fast enough to keep up. Your best bet is to add another large deep cycle battery. Solar panels recharge your battery/batteries when your boat is sitting and your equipment is not being used, (over a long period of time).

I bought mine a year ago and have been using a standard 12 Volt battery in my boat. Never had a problem and it does it all. I use it to steer my ipilot troweling motor.

According to the instructions, it should only be used for marine batteries when off the boat. If operated in a confined space it could cause an explosion.

Sorry, I don't know the answer. My boat has a dual battery 12 volt system. I routinely use the batteries (and run the engine) with the charger running.

Yes, But you will have to periodically keep re-charging that Marine battery! Hooked up and turned on means the Inverter is pulling a bit of current even when nothing is plugged into it, To not use up the battery you need to just turn it on when needed. Make sure you put fuses from the battery to the inverter also!

The motor will only run if the boat is in water. If you want to test the motor out of water you can touch both metal tubes (at the same time) on the inside of the boat to start a charge.

I had my batteries charged while the inverter was hooked up but it was not turned on while it was charging it didn't cause any damage to my inverter

When switched to on and you start your boat your alternator will charge that starting battery. After three minutes the batteries will be combined by the ACR and your alternator will charge both batteries. When you shut off your engine the ACR will isolate your starting battery so it can not be discharged. So listen to that favorite song track for hours till the battery is dead if it's that good. There will not be any issues with 11 volts it treats both batteries the same as far as voltage charging is concerned. Start your boat and your good to go. I would suggest both batteries be in good condition. This product is an install and for get. Best money you will ever spend.

I installed the charger on my boat,(near the battery) then installed a Marinco Marine On-Board Charger inlet(also close to the battery) to plug the power in to charge the batteries. I had to cut the ends of the charger off and replace it with a male plug in the on-board charger inlet to plug in the cord to charge the batteries. works great.

I have three batteries on my boat each is connected through an 80 amp continuous solenoid. The set up works fine it keeps me from having to open the hatch to turn the batteries on and off each time. ALWAYS remember to turn off when not in use or leave the battery charger on otherwise they will run the batteries down. Hope this helps. Charles

I say , yes . I have had mine out charging my boat battery for a couple years now . It is important to secure them well so they don't rattle around in the wind and break a connection .

Well I use this battery in a kayak to power the fish finder and I unload my kayak when I am done for the day and before I put it back on the trailer. I guess you could leave it in the boat if it is strapped down so it won't bounce around. It is a sealed battery so nothing can leak out if it is on it's side
