Questions & Answers

How could I use this in conjunction with batteries to power a 1000-watt HPS grow light?

We are not dealing with an inverter here. In this converter, 110 volts are converted to 12 volts. Although you could charge batteries by using it, and you could run 12 volt lights with it, I'm not sure why you would not just plug it into the 110 volt system. **If you would like to purchase an off-season ticket, you must When you are using a grid-connected grow light, you will need a solar charger, a large battery bank, and an inverter in order to convert all 12v into 110v power. Math will be required to figure out how many of each are needed.

The internal board blew a fuse after being hooked up to the 220 volt supply. Can you provide the schematic or parts list?

Chargers of this type are not meant to be used at 220 volts. When you go 220, it's going to blow if you've got 110 only

A car trailer with an enclosed cabin is at my disposal. Ideally, I would want to be able to plug it into 110 volts and have a battery backup to keep the lights on if I'm not plugged in?

If you want your lights to work regardless of whether you are connected to shore power or not, use 12 bolt lighting. It would be better to add a few outlets to the side that runs at high voltage so you can have 110 when you're connected. You may also want to consider using deep cycle batteries instead of an

In the event of permanently plugging into an RV park, is the use of a battery necessary?

The answer is yes, you can and I would suggest you put an automatic or manual switch on when connected to You will increase the life of your battery and inverter by having that switch. You can then use 110v plugs and accessories for short term power. As a result, the inverter, battery, and charger will be able to rest more and charge more quickly.

As far as I can tell, it deserves 6 stars
5/5

Despite getting there on time, the converter worked perfectly right out of the box. It moved right up to 14 because I had low batteries in my motorhome. After about 2 hours, the voltage dropped to 13 volts and then stayed there for about 5 more. The battery was at 8 volts for about 4 hours and then went to 13 volts. Since that time, the voltage has been at 2 volts. After a second day, I switched on all of the appliances and both tvs the furnace held steady at 13 degrees. The voltage is three Despite only having owned this Power Max Converter for a few days, I couldn't be happier with it at this point! This link leads you to a pdf that shows you exactly how to install it, it was very easy to follow and worked very well. I've had it for a couple of months now, and so far it is still performing well! There are [

I really like this unit! This use case makes sense if you understand it
5/5

As a replacement for my RV's factory converter, I installed this one. It is difficult to convert sound to electricity at the factory. This unit was installed in the front cargo compartment of my vehicle, and new 6 gauge wires were connected directly to the The fan speed cannot be changed, but it only turns on when it is needed, as stated in other reviews. This unit can run over 8 amps without the fan running at all, in contrast to my factory converter that runs the fan at full speed when it pushes 8 amps into the batteries. The capacity of this unit is three times greater than the factory unit, and it pushes three times the current into the batteries. The unit would be optimally suited for mounting in an area where there is a lot of cargo. I will be able to charge the batteries much more quickly if I am making use of the generator while dry camping.

That's a heck of a It replaces a "single-piece" that was damaged by unauthorised repair
5/5

This product was purchased for a reasonable price In an older camper, there is a "stage" charger and a power supply. I did not want to have to suffer the same fate in a new unit as the older unit's "bulk charge only" design contributed to the premature demise of several (horrendously expensive) deep cycle batteries. There are three components to this unit There should be a solution to that problem with stage charging. There was a slight difference in the dimensions between this and its open-plan counterpart This deck was designed to replace a deck predecessor that required some "engineering" of the enclosure. However, this was known at purchase and did not present a problem. I am amazed that you even know this. There is a moderate amount of noise, and is only active when necessary. Though I didn't open the unit to check out the contents, the solid metal case and the exterior connections from the outside indicate a similar high level of quality is present electronically. This perception is supported by solid voltage and amps output over the first two weeks of.

It is difficult to follow instructions
3/5

12/26/19 UPDATE I took a look at the instructions on setting this up and found them quite useful. Connect the charger to an AC power source and disconnect it. An onboard micro switch can be found on one side of the charger, which can be used to set the charger to "FIXED" or "3 STAGE". Grab a flashlight and a tweeker (a small screw driver with a phillips head will work best, or a very small straight slot) and get started. You want the micro switch to be fixed. While the charger is connected to the battery(s) and nothing is drawing energy from the battery(s) (this is called no load) and while the charger is connected to the AC supply, operate your multimeter on Volts DC (VDC), reading across both It does not reach 14 volts if the output voltage isn't The micro switch that controls the fixed / three stage operation on 4 VDC is adjustable. Please be careful! It's important to use gloves when handling these adjusters, they are delicate and prone to breaking! Ensure that over the output terminals of the charger the DC voltage does not spike. Turn the adjuster counterclockwise gradually. When you've set the voltage to 14, go ahead and press the start button. If you have a charger with an AC input of 4 VDC, please disconnect it. To enable 3 stage micro switches, change the switch to "3 Stage". Charge the battery again by plugging it into the AC outlet. Battery(s) should be boosted to 14 volts by your charger. If the voltage is greater than 4 VDC, then enter Now, I have the same problem as you. The world is now a happy place! In this case, I have this attached to a bank of three deep-cycle 13 is the end of the charge. There are two volts present. Based on this information, the charger supports all recharge modes (normal charging pushes the battery A DC supply of four volts. Set the batteries to equal (forces the voltage The acid and water are mixed with a 7 VDC charger and may be desulfated as well). There is a limit of 13 on this charger. It is powered by two DC batteries. A portion of the manual is as follows Adjust the voltage description for fixed voltages It has been set on three stage charging mode to begin with. In light of this statement, I believe the charging system is set up from the factory to provide the 3 stages In my opinion, I wouldn't recommend this Converter based on other customer comments.

It is best to be cautious when purchasing
3/5

Unlike many of the other reviewers that have purchased this model, I was disappointed to find that the actual amperage output did not meet the rating. I have also never been able to get more than 13 out of this unit. The battery bank voltage must remain at 6 volts no matter how much charge is in it. At 14, there was a failure to bulk charge. The battery is claimed to operate at 4 volts and possess a float charge of Your batteries will be sulfated and their life will be shortened. There is no need to use 2. Obviously, considering that PowerMax is notorious for its sulfating option, I just tripled my cost for new batteries and a replacement unit of another brand. Avoiding Powermax altogether seems like a good choice. However, as the stick on label suggests, this is a generic drug from China, like so many others in this price range. As with every generic drug in this price range, consumer beware.
