is it ok to use this with solar cells in a 24v setup or will 24v damage it??

My grid tie 300 watt inverter is connected to two 150 watt 22 volt panels. Working just fine at that voltage. The previous one burnt out with three panels connected to it. Apparently the voltage and amperage had increased when at full sun. I would consider de-rating all voltage values to 80 percent on any inverter you purchase.

I connect to 24v batteries rather than solar panels to get max 300w out. The batteries are solar charged.

as a previous owner of one of these i wouldnt recommend buying this inverter i had one and it didnt last but a few days on 2 100 watt panels wired paralell the most wattage i ever saw was 112 wats and 18.8 volts

I have 5 of these units working off of 24v batteries (really 24-28v) and get near 300w each. I use to charge my Nissan Leaf which is 1500w.

It will work - but be aware of "hyper-voltage'- on a cold, sunny day some panels will put out more than the voltage they're rated for. Of course, the answer is to unplug the panels. As a starter unit, this is OK - but the general advise is to buy the biggest unit you can afford. I bought one of these units and returned it for a 1000 watt 45-90 volt unit. they work nicely, but are pricey.

Hello. this grid tie inverter accepts 10.5VDC up to 28VDC. However, these units are not approved for most areas and honestly are not a very good product. I would not advise purchasing this unit. If you are serious about installing a grid tied solar system I'd reccomend doing it properly. Look into the outback grid tie inverters. They are much more costly but there is a reason for that. You get what you pay for.

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 found that to be normal though I have no background in electronics I did not have a problem because it does everything that was claimed. Another thing is that if it is close to discharge the solar voltaics will not charge it to 100%. It is best to charge it up if you are away from electricity with solar before you get to a total discharge....

I only tested the unit by hooking it up to my car batteries (two in serial for 24v DC) and it works. I suppose as long as your solar panels under the full sun won't exceed the the unit maximum input voltage ratings you should be fine. You can connect your panels in serial or parallel or in combination to provide the voltage within the range specified by the unit. Obviously it should work (producing power) during the day with full sun but voltage/current would tapering off (so as the power generation) when the sun goes down.

If your set up for 24v you have to disconnect cable. Otherwise you would have a direct short and ruin your charger. Maybe there are chargers out there that are 24v rated? Mine is set up for 12v (2 batteries connected parallel) , that is "+" to plus and "-" to minus. That way no disconnect is needed. Hope this helps...

I used this panel to keep the batteries charged for my gate opener. If you use this make sure you cover it to block the sun until after everything is connected. IE: Load controller and the load, batteries also if you are charging them. This panel puts out around 28V so it will fry anything that is not going through the controller. I charged to motorcycle size batteries, 24V kept them charged. Am going to use it now to keep the batteries charged on my Quads, I will reset the charge controller to use 12V instead of 24V Great little trickle charger and it will maintain your battery, Not meant to recharge the battery just maintenance.

Hello,If you are charging 12v nominal battery bank you can input up to 400 watts of solar power.If you are charging 24v nominal battery bank you can input up to 800 watts of solar power.The wiring configuration of the 800 watt panel setup must be done so that you do not parallel all of them or not series all of them or else the panels will either go out of the 100 VDC or the 40A rating.The 800 watt setup must be wiring in series/parallel.Please let us now if you have any further questions.Regards,AW

I purchased this after reading the other responses and can confirm. I'm using a single Solarworld 250w panel (24v) with two 6v Sun eXtender batteries (wired for 12v). Works great.

I am using a 100watt panel made by Global ICP. Is your panel 12volt output? It must be for this charger. The actual output will be higher but not over 24, which is the next stage up. My panel puts out 19.5 volts directly. If you have a muilti meter, check the output voltage if you do not know.Best to look around and get a book on solar. Plenty available. Learning first will help prevent mishaps or damage to your expensive equipment.

A test you can make is to directly connect the panel to the battery, correct polarity important or you will fry things. If the voltage is 17 volts or under you are good to go. If it is still over 18 volts you will be over current and ruin the battery. You cannot have the controller set to 24 volts for your 12volt battery!

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.

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!

12 volt battery would be ok. If the source is solar, be sure it really is no more than 12 volts. Many solar charging setups for 12 volt batteries could put out as much as 17 volts.

If you link directly to the solar panel battery-powered, I have a problem may occur when the battery is filled, and may cause damage to the solar panel, the best use MPPT Charge Controller I use this kind MPPT TRACER 3215RN Solar Charge Controller 30A 12V 24V EP I do not use the conduit You got an answer, if you did not get the answer for that, please send a message again

I confirm what it as been said before by the others, no problem unless you use it with a very sensitive equipment. Another way to do it is to use a 14v adapter to get 12v at the end if you have a voltage drop. But normally the equipment have a tolerance and you should be good.

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.

Do not hook up to 24 volts, it's For 12v to 13.5 dc volt . You can find good one inverter 24 volt @ http://www.theinverterstore.com/2500-watt-power-inverter-24-volt.html
