Can I use this with my 18-19v solar panels?

Most likely not. For an inverter like this you'll need to connect them to batteries, and most solar chargers need a panel voltage higher than the battery voltage. You could, however, put your panels in series to increase the voltage as long as the combined voltage still falls within the solar charger's input specs.

No, the "low voltage" alarm would go off. You need panels that will output 23 to 26 volts to power this inverter.

I can confirm Renogy Solars answer (it'll work with either 12V or 24V battery banks). I use this panel with a MPPT controller and a 12V battery bank.

yes you can,I bought some solar lights that had very low voltage batteries and it charged them just fine.

As long as you put 12 volts in to your batteries from your solar panels and draw off your batteries it will work just fine.

No idea in a solar panel use but they are 12v. So If the panel is 12v you may need to adapt it some how

Can't help on the solar panel. I have used the 12v option off of my house batteries. The unit worked fine

I am using this with a Grape 250 W 30.7 V solar panel with no problem. On clear days it is not unusual to get over 33 V. This has no problems with it. I'm certain I could put another in line and still be fine.

I'm really not sure if you can use a non-Earthwise battery; but as one reviewer suggested, another 18 volt may work as long as the base (part that plugs into the unit) is the same. Also, the battery would have to be a NiCad, as you cannot use a Liithium battery on a NiCad system.

Yes BUT... You have to buy a charge controller that can "step down" the 36 volts from the panel to 12 volts for the batteries. Look at Morningstar controllers and or go to Morningstar's website to get the specs on an appropriate controller for your application.

Yes it will work. The "20 Amp" rating refers to the amperage produced by the solar panels, so if the current produced by your panels at peak efficiency is below 20 amps (and off the top of my head, it is) you will be fine. Remember to hook this up in the EXACT order as the instructions say or else it ill blow a fuse. Good luck!

Unfortunately I haven't installed my solar panel yet. So I cannot answer this question.

You are more likely to over charge the battery with a 12 volt unit. Just ensure the whole solar array is in the sunlight for optimal charging.

Look on the adapter and it will tell you...I believe it is about 20 volts...you could definitely make a solar charger...the other option, one I use, is to use a 12V to 120 adapter and then can plug any 120v appliance in to the standard outlet...obviously within the wattage of the solar panel and adapter...and it will exhibit some loss...typically about 20%

Yes, you can use this for anything that requires a 12 volt input, just keep in mind you want to keep the load at or less than 75% of maximum. Although mine has been operating just fine powering my led controller and 150 watts of strip lights

Sure you can. I use it at 18v and get about 4.5hrs out of mine. Great little battery.

Yes, I use that size panel too, inverter works good. Any panel voltage should not exceed 60 volts, watts should be well under 600 watts, so no more than 2 of those panels

I don't see why not. Just make sure the total load is within the limits if your inverter.
