24v solar panel: Can i use this controller with a single 24v 100w solar panel to charge a 12v battery?

What you want to do requires an MPPT controller. This controller is NOT an MPPT controller.

It is my understanding this unit can work for both a 12 v and 24 v system. I think that you might be confusing the one with the other. On one side you have the system charging via the pv modules there is a max input voltage of 100 volts . And on the other end you have your voltage bank. This unit supports a 12v, 24v, and 32 volts bank. The choice is yours. If I can be of help email me at Edgib@bellsouth.net.

Yes you can however you will need a controller capable of handling both panels. Most small inexpensive charge controllers handle 7 amps or less. Two 60 watt panels will produce more than 7 amps on a sunny day.

Freddy, Yes you can connect 110Volts and 24 volt battery. In this configuration the 110volt charges the battery. NOTE In this configuration the battery acts as a backup in power failure when 110 volts go out. You cannot use solar support - panel charger etc. 2. The LM 118 is the recommended Charge Controller but it seems like (1) the batteries aren't being charged properly or (2) the batteries are losing power somewhere. In the night the batteries would discharge through the solar panels but the charge controller should take care of this. What you can do is monitor the voltages over one night. Check the battery voltage at early night 6:00pm and in the morning when it does not open the gate. Then the second night disconnect the solar panel and check before and early morning again. If there is a stark difference you may need a higher specification charge controller. Also (3) make sure the solar panel is charging the batteries to their full capacity. A proper panel should deliver between .5 amps to 1 amp at hot sun to charge the batteries properly. I hear the solar input is not an effective input. The power of the gate opener is reduced through this input since the unit is compensating for this low power input. As you have explained I would condemn the solar input. Connect the 110 volt and connect the 24 volts to the battery input. The 110 charges the batteries to full power and when power goes you have the fully charged 24 volts to take over. Also, sounds as though your solar kit is stronger than the ones in the Aleko kit. The solar remains a great option since it is the main quality of this opener. Experiment with the efficiency of the kit and when you are certain of its reliability then you can connect this option. The charge changes with the sun intensity. Dull rainy days will not allow proper charge etc. All in all it is a well designed and full featured item.

Yes it is fine. Most solar panels have or need a charge controller because they put out 24v. This panel has an integrated controller, and will automatically adjust to a 12v (or 24v) battery system.

The solar panel voltage must be higher than the battery voltage you are charging. A 12Volt (open-circuit about 18 Volts) solar panel will not charge a 24 volt battery.

It's made for a 24 volt charge controller. If you just have a 12 volt controller get 2 100 watt panels from home depot and wire them in parallel.

Most larger, more powerful panels are 24-volt. A good charge controller will automatically step the 24-volt down to a 12-volt battery. I don't know off hand if the HQRP will do it -- it seems to say that it does, but you might want a more expensive controller, a MPPT controller. Also, if you have 150-watt+ solar panel, a 10-amp charge controller is too small, as you probably already know. You'll probably want a 20 or 30 amp.

Assuming both batteries you're hooking up in series are 6 volt and of equal capacity and condition then yes, they should charge just fine with a single 12V controller. However, keep in mind that mismatching the two batteries in respect to capacity or condition can dramatically limit the overall charging capacity and run time of the entire string.

You can hook 4x100w in series or 2 sets of 2x100w in series/parallel with this controller. Adjust your fusing and wiring accordingly. I intend to add the extra 2x100w in parallel with the existing 2x100w set I have. I should mention that my system is setup to run as 24v (panels, batteries, controller and inverter (240vac out)).

Since the Controller os automatic Voltage sensing on the Battery Side, the answer is NO. The Controller will sense a 12v battery system and will shut down, as in overloaded. The Controller will allow you to hook up to a 24 volt solar panel but the max input into a 12v battery system is 390 watts (30 amps nominal throughput to the batteries).

The short answer is YES, if connected in parallel.... BUT if you are trying to charge a 12V battery system then you will be losing about 70% of the panel power and I highly recommend contacting us to size you into the correct MPPT controller. Obviously you are getting a lot of incorrect or incomplete information. IF you are charging a 48v battery bank then this controller is fine. ML SOLAR

You can use this controller for 12v but there will be power clipping. The best controller would be the Outback FM-80 for 1KW solar panels charging a 12v battery bank. Thanks, ML SOLAR

Unless one has extensive knowledge of Solar panel and the Battery and Know how Solar Electric Systems work. I Do Not Recommend Charging a Battery without a charge controller. This panel is a 24v panel and will charge a 12v battery provided a MPPT charge controller is utilized. Appropriate MPPT charge controller for this panel would a Morningstar SS-MPPT-15L, this charger can accept up to 36v from the solar array and can charge a 12 or a 24v battery automatically.

I use my charge controller with a 12 volt converter, but I think you can put as much power in as you want,and that it will charge a 24 volt battery bank.Since I have 12 volt converter, I had to put all my 12 volt batteries in parallel, so as not to go above 12 volts and exceed the converters volts

I have six 100 watt Renogy panels wired for 24 volts. The meter that came with this controller reads almost 40 volts. It varies from 30-40 volts depending on battery state of charge (I am using six deep cycle batteries...12v). It works great. Additionally, I have pulled 34 amps down from the high sun which equates to around 815 watts. My unit has NEVER shut itself off. When the batteries are fully charged it will still provide power to your accessories. I am using an DC-AC inverter...so, it really doesn't matter.

There are two types of charge controllers; PWM and MPPT. I have 3x 100w panels ran in parallel to triple my charge amperage. This maintains the panels at 12v, but triples the amperage. I have a 30a charge regulator, which is PWM. I have read, though, that MPPT is the newest and best charging technology available. The PWM regulators are cheaper, but you get what you pay for. My next charge regulator will definitely be a MPPT. Google it. You'll figure out the difference between to two. Just be sure that you size your regulator bigger than your solar panel array for room to grow, and so that you don't constantly put your charge regulator under too much stress from incoming amperage. Here's the charge regulator I purchased http://www.play.com/Electronics/Electronics/4-/46835087/789550567/TomTop-30A-12V-24V-Intelligent-LCD-PWM-Solar-Charge-Controller-Solar-Panel-Battery-Regulator/ListingDetails.html?_%24ja=tsid:13315|cat:46835087|prd:46835087&ef_id=Udt8FQAABKfxcsgO:20130709151438:s It works well, but now is starting to be a little troublesome with the display just after 9 months of use. Spend a little more money and get one that is MPPT, and make sure you have an LCD screen. It's nice to know the charge, draw, and basic voltage of your battery bank.
