User questions & answers

Question:	Does this supply 500 watts through the cigarette lighter
Answer:	Only technically yes, if your cigarette lighter can deliver 49 amps. The cigarette lighter in our car is powered through the ignition switch and has a 10 amp fuse on it. Those 10 amps at 12.6VDC translates to about 100 Watts at 115 VAC out of the inverter.
Question:	How long will it power a modem/router
Answer:	It depends on your power Source ... the Battery. But for a modem ... for a Very Very long time indeed : ) I use it to power a mixing board for sound applications and it's Great for several hours using a small emergency battery intended for lights. The word EXIT might come to mind here : )
Question:	Will this power and run a 32 in tv with a cd player. Tv is led
Answer:	Some electronic device require pure sine wave AC. Or else ... smoke
Question:	What is the no load power draw
Answer:	“No load” power consumption is the power consumed by a device when it is plugged into a power outlet. In this case, I think if you are not “plugged” into one of the Converter outlets the “no load” consumption my be affecting your battery (power source) only. Additionally, the Coverter must be turned on.

User questions & answers

Question:	When using the 12 volt setting, what are the amps
Answer:	I haven't used or tested the 12 Volt setting. However excluding losses a IxV=W, so we can substitute and get I=W/V which in this case would be I=12/12, so theoretically the maximum current at 12 Volts would be 1 Amp.
Question:	I have no idea what "inner positive" means, so how does one know if they have a device that is inner positive? all the connection says is 4.5v dc
Answer:	This can be tricky in some instance.. This unit has a (+) positive inner, and a (-) negative outside. Which means the female of the plug is positive, and the male ( outer metal) is negative. Now tricky part, some devices use outer ( positive "+") and (negative" -" ) inner. I ran into this with some light, and score board. I bought generic transformer on Amazon, and none worked. took apart light , and found the polarity was reversed. This is how OEM folks fool conservatives that don't buy OEM parts, or know how electricity works in dc circuits. (Had me confused for an hour or two) OEM= Original Equipment Mfg.
Question:	i am looking for an adapter which would output 12v at .5A. Can this adapter do that
Answer:	Hello Leno,Yes, it can. FYA, find a suitable adapter plugs for your device.Hope this helps you, have a nice day!
Question:	I have a 4 ft Gemmy indoor inflatable football player that needs a 12 watt charger. Anyone know if this will work
Answer:	Not 100% sure. List three points to help you distinguish if it's compatible...1.Polarity: inner positive2.Meet the working requirement of 12W charger, be aware that the maximum current is 1.2Amps. (If needed current exceeded 1.2A, please search: SoulBay 30W Charger.)3.Find the suitable adapter plug,6 Connection Tips Spec.: 2.5*0.7mm, 3.0*1.1mm, 3.5*1.35mm, 4.0*1.7mm, 5.0*2.1mm, 5.5*2.5mmBesides, Should you have the detailed sticker of your original adapter, please keep free to contact us at [email protected] this helps you and best wishes!

Product description

Designed to give you options, the Renogy 30A Dual-Input DC-to-DC MPPT On-Board Battery Charger can charge a service battery in two different ways. The multi-stage charger can utilize connected solar panels or an alternator linked to a starting battery. While your vehicle's alternator prioritizes your starting battery, this unit will allow your solar system to charge your service battery first! It's the smart way to keep yourself fully charged and off-grid longer! With multi-stage charging and multi-chemistry functionality, Renogy's DC-to-DC MPPT Charger has you covered whether you're using Flooded, Gel, AGM, or Lithium batteries. Now you can unlock monitoring and control features exclusively using the BT-2 Bluetooth Module and Renogy DC Home App!

• The Renogy DC-DC On-Board Battery Charger with MPPT is designed to charge service batteries at the most efficient rate from two different DC inputs, solar panels, and the vehicle's alternator
• Compatible with multiple deep cycle battery types: AGM, GEL, Flooded, and Lithium
• Sophisticated automatic 3-phase charging profile (Bulk, Boost, and Float) ensures your service battery will accurately charge at the correct voltage levels to 100%
• Built-in Voltage Sensitive Relay (VSR) for user-friendly setup with traditional alternators
• Smart Protection Features: battery isolation, over-voltage protection, battery temperature protection, over-current protection, overheat protection, reverse current protection, solar panel and alternator reverse polarity protection
• Power source type: Solar Powered

User questions & answers

Question:	Can you use this with one 24v 300watt solar panel
Answer:	No. Here's why. The device can accept at most a 25v input into its solar terminals. And solar panels, be they 12V or 24V can invariably produce more voltage than they are rated at--much as the maximum voltage of a 12V solar panel will not exceed 25V (it might make 18V in some cases.)
Question:	can you use 120 to 12 volt regulator 40 amp to charge this instead of solar
Answer:	The correct answer is yes. The reason why this is so is because the controller inside the product is of the MPPT (maximum power point tracking) type, that can convert volts to amps or vice versa to maximize the watts (which is volts X amps) used to charge either house or starter batteries. A more to point question might be if it is recommended. The short answer is I don't think so without at least knowing the size of your house and starter batteries or what you draw in power from either and when (engine on or off.) Knowing such 411 allows for the proper sizing of your power source, A/C charger and/or solar panels alike.
Question:	How does this work for smart alternator? Can you connect this to the start battery directly
Answer:	Yes, Connect to the (+) terminal of the start battery through a 45 amp fuse for the 30 amp Renogy (75 amp for 50 amp Renogy). Negative lead to (-) terminal. For a smart alternator, you must use the IGN port (Ignition Signal Input) on the Renogy to turn the charger on/off. For a standard alternator, do not use the IGN port as the charger will sense the alternator voltage and turn the charger on. With a smart alternator, the vehicle may be operating at 12V for fuel economy. This will confuse the Renogy input voltage sensor and the charger will not turn on. I use one of the four GM Upfitter switches on the dash to control the IGN. Some people tap into a vehicle cargo light switch 12V output.
Question:	How do you connect it to a fuse box
Answer:	You want to connect the charger to the house battery that you want to charge directly. I put inline breaker fuses coming from the solar panel and alternator to the charger.

Once the battery has reached a 100% charge, the chargers will automatically switch it's output voltage to a safe, storage/float level (13.6V+/-0.2V) that eliminates the need to worry about the damaging effects of overcharging.

Pulse Current Recovery Mode:

In the Absorption Mode, the charger will give a 0.5Amp pulse current to charge and recover the battery until it's fully charged. In this stage, the charger will decrease the battery sulfation and improve the battery performance gradually. For several times charging, you will find the battery internal resistance is lower and the performance is improved.
