Seems to me I could route that 12v output to a good MPPT Charge Controller attached to my travel trailer’s battery system to charge the batteries. 94 $64.95 $64.95 Your thoughts on this would be appreciated before I purchase a pricey MPPT unit. Or more likely: The inverter within the generator could not act as the channel between your battery and your AC appliances. The best way to charge your battery is to run a proper 240-volt or 120-volt battery charger off the generator’s AC output. Can you suggest anything? Notify me of followup comments via e-mail. I would like to run a 200W 12v motor on an olive picking machine and wonder if there it can be run off the 12v outlet on a genrator rather than having to us a battery? In other words, if I connect a 4KVA generator to charge the inverter batteries while 2KW is being used by the normal load, would the generator shutdown because of overload or would the inverter slow down its charging to run the normal load? Remove any spilled acid or corrosion from the top of the battery. In our experience, using a good quality 240V charger is a very safe, quick and effective way to charge your batteries. Confirm that the battery charger is operating by inspecting its charger condition light. Charge batteries in a well-ventilated area. A typical mobile generator’s nominal 12-volt output while charging a typical RV’s battery is about 13.6 volts. If the fluid level is low, fill it up to the ‘Full’ point with distilled water. Interesting you talk about using a 240 VAC charger as most people would have a 120 VAC charger, but either works and all generators have 120 VAC. Thanks Paul, Honda recommends that you keep the battery fully charged at all times to achieve maximum service life. Does your generator produce pure sine wave power? Hi, in terms of battery charging; provided I am using an AC outlet with a quality battery charger, do I need to disconnect my main car Battery before charging it with an inverter generator like the Yamaha 2400? Attach the black clip to the negative terminal on the battery. After that charging … Yes, this will be suitable for your application. Hi Sean Also, most chargers regulate themselves down, so as charge builds in the battery, the charger won’t be pushing the same amount of amps. Car weighing about 170kg .. Never smoke or use open flames around batteries or gasoline-powered generators. I have a 3.6KVA inverter connected to four 150AH batteries with a charging current set at 12A. Suggestions? They will charge at a rate of approximately 2.5 charge/second in charge nodes and 2 charge/second in city terminals. 99. Battery acid is corrosive. Let’s get straight to point: camping generators may have a 12-volt output on them, but when it comes to the crunch, they are not designed to fully charge your batteries directly. Attach the red charger clip to the positive terminal on the battery. The next step is to attach the cables again. Inspect the deep cycle battery liquid level periodically, and add distilled water as needed. I have a solar set up with 6 110Ah batteries (12v 600Ah) and need a back up charger, I need a generator with enough output to run a battery charger, what would you suggest?? The camper is rigged with two CTek chargers, namely one 240V Multi XS 15 Amp charger, for powered sites, and a Dual 250S DC-DC charger for recharging via the car’s alternator. You may have to contact the manufacturer of the charger to see if they can shed some light on the issue. Secondly, the voltage of the DC output isn’t regulated – it varies according to the generator’s RPM. To charge your battery bank up to 100% full would take considerably longer and really is wasting fuel. The investor powers my air compressor, table saw and any hint else I plug into it, but will not power the charger. Also, the generator won’t cut back the charge when the battery is nearly full, so you can’t risk leaving it charging for too long. They can also be filled by the following creatures: Charging batteries up to around 90% is the best compromise if you want to run the generator for as short a time as possible. If so, matching a charger to a generator becomes less risky. This wattage information can be found in the product manual, on the product data plate, or you can contact the manufacturer to ask them. However, we supply conventional generators for all manner of battery charging (including solar systems) without issue. So any battery will take a while to fully charge. What type and specs of dc generator is required for charging a car battery??? In terms of wires for your Honda 1000, we would advise you opt for a Honda 12Volt DC Charging Lead – for Honda Generators, these need to be purchased separately. However, if you are confident that your DC to DC charger correctly regulates the charge (which it should), then it would most likely be fine. Make sure you get the starting wattage (this is the most important) as sometimes the specs will only list the running (or rated) wattage. Attach the black clip to the negative terminal on the battery. I also have the yamaha 2000 generator pictured in your post. Charging a gel battery with a lead acid charger is risky, since gel batteries require constant voltage charging, versus taper charging provided with lead acid chargers. Has anyone ever charged your vehicle with a portable generator? If A 1000watt Gen can do the job in 8hrs or so I am satisfied with that. There is an inverter involved in my system .. You do it by using a high-quality 230-volt battery charger run from the generator’s 230-volt output. And because your RV’s built-in battery charger can utilize up to the full 2,000 watts available from your generator (actually, 1,800 watts in most cases, but who’s counting), on the 12-volt DC side of the converter/charger you could easily be charging your batteries at up to 160 amps of current (2,000 watts / 12 volts = 166 amps). I am interested in Saving Weight and Efficiency. BRAVO FOR A REALLY IMPRESSIVE SITE. It’s true the charger would regulate the charging to proper levels and should be used for those reasons. So I’m not looking for a full recharge, just enough to bring a healthy amount back into the auxiliary batteries, for the next day’s draw. Alternatively, I would need a separate Inverter. Again, you are best to check your charger to see if there are any specific power supply requirements. The main use of the converter is to provide 12 volt power for your rig while plugged in to an A/C outlet. Plug the battery charger into the 110-120 volt AC outlet on the generator. The first step is to look into the electrolyte level. jQuery("#blog_promobanner").slick({ The bigger the charger the quicker you can charge your batteries. Do you know the peak power draw of one of those chargers? Mark. Automatic Stored Battery Trickle Charger for Portable Generator, Car, Boat, Motorcycle . You can also watch the below video from our friends at Enerdrive (who make excellent AC to DC Battery Chargers for hard wired installations) demonstrating their ePower chargers: If you’re looking for a plug & play option, you can simply plug a good quality smart charger into the AC outlet of the generator and connect the 12V charging cables to the positive and negative terminals of the battery. Thanks, Steve. My main questin is, what mode would be quicker/more efficient to recharge the battery, a) using the 240V power lead into the external socket on the Camper, or b) running the DC lead into the input side of the DC-DC charger? It needs to be under 2000W. If the engine was equipped with a generator to charge the battery, it will charge the battery, given enough time. As usual an American who thinks they are the only people in the world. Hi Steve, This will recharge the battery much faster and accurately. Hi Bill, to run 12volt appliances it’s advised that you use the AC output of the generator and then an inverter. So it would be ideal to use as a battery charger with the EF2000IS, Feel free to call me on 1300 400 122 for more charger options and information. Thanks,Karl. When your done with it turn off the gas and let it run its self out, that way you don't leave gas in the carb which is a problem over time. Some switch mode chargers like yours require pure sine wave power. If not, what size battery should I be looking for? Sean is the co-founder and Director of My Generator (mygenerator.com.au) with a keen in interest in the outdoors and power products. I have a 72v 100Ah battery pack with a 30amp charger. And the reason the manual says if it is to low it needs to be charged is because if it is to low you will not be able to start it with the battery. The AC is then conditioned with a regulator-rectifier to create a DC current/voltage required for charging a battery (see figure 2 below). I wish to run a 1kva inverter generator, not any larger or noisier than that, to power a 12v or 24v proper battery charger. The DC output of a generator provides unregulated power and is really designed for small trickle charge (say a flat car battery) purposes if required. Review the battery charger instructions for descriptions of the lights or gauges showing the status of the battery charger. I recently bought a Gentrax 3.2KVA generator for the purpose of doing odd jobs on my block of land. Attach the battery charger alligator clips to the battery terminals. Cheerio, When you charge a battery, you are sending an electrical current through it and the battery is converting that current into stored chemical energy to be released at a later time. Stand alone pure sine wave inverters of about the same output as the Gentrax 3.2 kva are only about the $300 mark, Make a mistake with the Gentrax inverter module and that would cost about $600 to replace. I am at a loss here. Hi Norman, it is important to match the battery charger to the generator. We would like to connect an AC industrial generator as a backup to charge the batteries (Pylontech New lithium 2.4kWh( 2 x 48/50Ah) Phantom …
