![]() A fridge, AC, or anything with a motor has a surge at startup, quite often that momentary surge can be 3X the running amperage/wattage rating. You will have to identify the surge values as that will put amperage demands.You will need figure out / estimate how much power you will need for a full day out & about.Now to help you we need to bring you back to a point. BTW Primus is one of the "few" who are tested & certified and do perform exactly as designed. The Marine class Turbines like the Air-X from Primus when installed properly on a boat can work very well indeed. Many folks do not get the difference between using Wind on a boat versus land based. Wind power is possible but due to space limitations for large blade area power is limited to low levels. You don't say what size and type of sail boat but mounting panels is a challenge as shading and space is a problem. The basic requirements of the boat electrics is to power the boat engine and navigation/ radio equipment. The boat engine battery should be seperated from any house battery. Start with a simple system and progress with experience. You seem new to sail boats and electic systems. Once you have the monitor installed a few trial runs will give you data on typical day use.Ī 2000 watt inverter at full power is a very heavy loads for 200Ah of AGM battery, this will take around 200 amps on a 12v system. Your sail boat should have house batteries installed and a control distribution system for the various electrical items, usually with some indication of volts and amps. The Victron Smart Shunt is good value and much much better than the low cost units. Hope that I am helping you so you can help me! LOLīuy the Victron battery monitor with the 500 amp shunt, this will be adequate for most systems. What's the best way? A battery monitor right? Whew. As for now I just wanna know what I use so I can overbuild a bit. I think it is best to save that for later. It also has a shore power connector that charges with a 40A charger. So I am not too freaked out about running out of battery as I can just start the engine. I can build the system For now, the only charging available is via an alternator attached to the engine. Once I know what we spend in a day/night. I thought maybe getting a monitor to monitor the battery as we use the batteries and record it would be a good start to building the system from the ground up so to speak. I was thinking 2000 Watts of inverter is more than enough for an icemaker and some other stuff. Install an inverter and have a cool cruising boat.īut I don't know diddly squat about what I need for solar because I don't know how many amps I use in a day. (Will try to build my own lithiums later in life) giving me 200AH at 12vdc. So.with that in mind I was going to start with two 100 amp hour AGM. Idea is all of it to be solar and just have the wind to be there. Please this is not a debate of whether wind is a good idea. I want to eventually end up with enough solar to power my wifes and I requirements for a day of sailing. Haven’t been able to take it on a trip yet, but Spring is coming and it should be awesome.Probably cause I have no clue what I am talking about. I used a 3M product called Dual Lock on the bottom of the battery to prevent it from sliding on the floor – it’s similar to velcro, but not the same at all. ![]() Shout out to my son the aircraft mechanic for providing the fancy Elcon bulkhead connector for the battery cables – makes for fast and easy battery removal. Here’s a couple of pictures of my setup – one view from the storage compartment and the other of the backside of the bulkhead where the cables are routed and the Victron is mounted. I’m just learning about lithium and battery monitors so I had several questions for the guys at Dakota and they helped me get this project completed and working perfectly. Was able to relocate the battery from the trailer tongue to my front storage compartment and keep all the wiring neatly tucked away – as well as clean up the factory wiring mess I found during the conversion – typical camper crap. Converted my RV from lead acid to lithium with a Dakota 280 Ah battery and a Victron Smart Shunt.
