will this hurt my charge controller for solar? if they are both charging?

It should be OK, so long as only you are only using the one charging source, in your case solar. If you choose to use both the vehicle charging system, and solar, I would add a switch to separate the two different charging systems.

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.

Absolutely. Just make sure the solar charge controller is 12VDC and rated appropriately for the output of the solar panels.

Are you getting the red flashing light indicating it's solar charging? Since it sounds like you have a problem, you should contact the company? I would do that immediately and see what they say.

The battery is just a normal nimh type battery so that is the issue.Take the solar part out of the equation and treat it like its just another charger.

You're probably thinking of a charge controller, not an inverter. And yes, you always need a charge controller so you don't overcharge the battery with the solar panel

Thank you for your question.Deltran, the manufacturer of Battery Tender products doesn't recommend using two charge controllers on the same line. There is no need to have one charge controller in line with another. Make sure you use a charge controller rated for the size solar panel you have. NOTE: You can use multiple solar panels to charge a battery or battery bank and each panel can have its own charge controller. Just don't put the charge controllers on the same line.Thanks again for your question

These connect to the supplied (or a replacement) charge controller which connects thru a fuse to your battery. If your generator also charges the battery then this charge controller simply will be over shadowed by the generators charger (as in at night). I have it connected this way and it works fine. (Both chargers in parallel with no issues.) I'm keeping this charge controller as a spare and have replaced it in my RV with http://www.midnitesolar.com/pdfs/spec_sheet_kid_frontBack.pdf. I ended up getting a total of 4 of these panels for a 400W system. The Kid essentially adds another virtual panel due to it's improved efficiency.

I am using the panel connected directly to a large, deep-charge battery, and it works OK. You can go through a controller if you are worried about overcharging your battery.

yes the voltage output will vary with the amount of sunlight. I have my panels setup to produce a max of 36 vdc charging a 12 vdc battery bank. your charge controller needs to match your projected final system capacity, if there is a possibility of adding on later. I have a mix of 144s and 88s

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!

It all depends on which charge controller you choose. If your charge controller is rated for 24V then you're good.

The plug-in charger only puts out 2 amps. If your solar panel USB port has similar output there should not be a problem.

If the two are connected it sounds like you are running a 24V system if that's the case I wouldn't use this one. Other brands make 24V onboard charges.

No ! The charge controller should be mounted in a dry , cool place . The PV cable supplied is of no use , unless you are mounting the panels on a garden toolshed roof and installing controller , batteries and inverter inside the shed . Since my panels are 50 feet from my charge controller , I am using # 10 awg pv cable ,very little power drop ; charges my batteries fast. Hope this helps . ..Roger

I have read somewhere you should connect the inverter to the battery. Because of the potential load you are pulling could exceed the charge controller. I am just passing on what i read just got my panels will be installing them soon

I have 40 amps of power so I have 2 controllers tied parallel to my batteries. Yes, you can use two separate solar arrays connected to two controllers. Just make sure that your solar panels stay under 30 amps per controller.
