Will the controller work with a 25 milliamp solar panel ? It only seems to be putting out 2-3 volts with 13 volts coming from the solar panel.

My understanding is that with that low of an output you would not need to worry about overcharging unless you have a VERY small battery bank. The charge controller (non MPPT) is pretty much used to prevent damaging a battery (bank) through overcharging.

You've probably checked on line, but this is a good site to referencehttp://www.chargingchargers.com/tutorials/solar.html25 milliamps is really small, and may not generate enough watts to bring the controller into play.I connected the controller to a largish solar panel, output approx 20 volts, for keeping my boat battery topped up.. the combination seems to work well at this level.Hope this helps.

to get an actual through-put reading, you will need to disconnect the feed from the panel(s) to the controller, then disconnect from the controller from the batteries. after that re-connect the solar feed to the controller and measure the voltage on the disconnected lines to the batteries. you must do it in this sequence. i had mine for about two years and it quit working. naturally, the controller was the last part of the system i checked. i went back to a seven amp controller for my two 55 watt panels. i have three batteries that charge quite well and provides light in the downstairs plus it recharges all of my battery operated devices - tools and so on. good luck! to get an actual through-put reading, you will need to disconnect the feed from the panel(s) to the controller, then disconnect from the controller from the batteries. after that re-connect the solar feed to the controller and measure the voltage on the disconnected lines to the batteries. you must do it in this sequence. i had mine for about two years and it quit working. naturally, the controller was the last part of the system i checked. i went back to a seven amp controller for my two 55 watt panels. i have three batteries that charge quite well and provides light in the downstairs plus... » Read More to get an actual through-put reading, you will need to disconnect the feed from the panel(s) to the controller, then disconnect from the controller from the batteries. after that re-connect the solar feed to the controller and measure the voltage on the disconnected lines to the batteries. you must do it in this sequence. i had mine for about two years and it quit working. naturally, the controller was the last part of the system i checked. i went back to a seven amp controller for my two 55 watt panels. i have three batteries that charge quite well and provides light in the downstairs plus it recharges all of my battery operated devices - tools and so on. good luck! « Show Less

I think you need to check your controller specs, but I know some controllers may just shut off to prevent damage. Also note these panels are higher voltage which may not be compatible with your controller. I bought a charge controller that won't work with these because the voltage may go up to 45V on these panels. Now I run two of these with the Morningstar MPPT 45A charge controller. Morningstar has a calculator on their site that will confirm whether a planned setup will work with their charge controllers or not. I am planning on adding one more panel to my setup. The 45A MPPT charge controller can handle 3 of these panels. Good luck!

Yes, it will except 30 volts. The open circuit voltage of your panel will exceed 30 without load and cause a fault. A 12 volt battery will have to used since this controller is designed for lighting after dark.Mike D

this charge controler will work for a 24 volt system. that being said, you did not state what you are doing with it. i would assume you are charging batteries with your solar panels and that you intend to get a lot more in the future. if this is all the panels you are going to use with this controller, it is way more than you need. since you are a first timer, i would urge you to consult with someone in your world that knows solar and electrical hook ups. do this and save a bunch of time and money, and your safety. best of luck!

It is rated for 10 amps input and output. If it can handle 48 volts (which I don't know because I have a 24 volt panel) it will receive 48 x 10 or 480 watts (volts x amps equals watts). However, if you are charging 12 volt batteries it will only put through 120 watts. I ended up trading this in for a 20 amp controller because of this. I am very happy with the 20 amp controller.

Those two panels if in either series or parallel will still be over the max rating for the Midnite Kid 30 Amp controller. You can test this by using their Midnite Solar Kid Sizing Tool. However, the system will work if you switched your battery bank to 24v.Thank you,AW

Hello,For x4 of the 250 watt panels would be too much power for the controller to support in 12v let alone in 24vThe minimum you should go to run these on 12v would be roughly 96 amp controller such as the MidNite Classic.Please let us know if you have any other questions.Regards,Austin WaltiRenogy Technical Support Rep.

Yes. It will work with any solar charge controller. Just make sure the charge controller is rated for the total Amps required. The more panels you link together the higher the amp rating for the controller.

For one panel any controller that will handle 3 amperes or more. The max output is about 2.8 amperes per panel. More panels in parallel then add up the amperes

This model will handle a maximum of 100 volts of DC output from your solar panels, so your 48 volts is well withing its limits. If your system uses 12 volt batteries, which is most common, and your panels produce no more than 130 watts of maximum power (260 watts if your electrical system is 24 volts) this controller will do the job well. This is a great little controller and I'm totally satisfied with it, and the price is very fair.

Unlike many solar controllers that clam to be MPPT, this controller is a true MPPT controller and I recommend it. Per your question, I have no idea what you are trying to accomplish. db

I have 820 watts of solar and I have the Morningstar MPPT 45 with 6 batteries and works fine. The mppt 45 will only allow me 45 amps, but if I produce more it will not hurt that controller.

One 85 watt panel Should deliver around 7 amps at 12 volts in full sun. If you have all 4 panels connected through a single (7 amp) controller, it is way overloaded. Sounds like you might need 3 more controllers or simply a bigger controller unit.

Look at the max amperage of the solar panel and multiply it by 4 if this exceeds 30 amps you will need a larger charge controller. Without knowing the max amperage of the solar panels my best guess is that it will be close. I suggest getting a larger controller.
1283048
A 30A Charge controller WILL be adequate and will work but it is a narrow margin for your 145 watt panels. I estimated the amperage on your panels @ 7.25 amps each, that put you right at 29 amps. Barring any solar fluxes that might tip the controller to temp shut down you should be ok.

Hi Getpreparedstuff,Are you able to share with me the model of the solar charge controller that you use? Thanks. -David

Yes you can get a close approximate figure but solar conditions vary constantly. I turned on everything in my shop so the inverter called for a lot of amps from the batteries and thus the solar controller increases the amperage output to the batteries. Take the amperage figures from the LCD display and multiply it by the voltage of the batteries and that will give you the amount of watts being used at that time. In other words if your LCD meter says the batteries are getting 35 amps charge and you have 13.6 volts to the batteries then 35amps x 13.6volts = 476 watts being utilized from the Solar Panels. This is only approximate because there are various losses but the figure will be pretty close. Yes you can get a close approximate figure but solar conditions vary constantly.
