Anyone using this unit with panels above 100 watt/18 volts? Specs a bit confusing. Can I use this with a 250W- 29.9v PV?

Hello, I am using (2) 250 watt panels with four deep cycle battery bank and it works great.

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.

Yep. Limit for a 12V system is 260W. As it's mppt you can run up to 150V and it will break down to feed the 12V converting the excess voltage into amperage so you have to consider limits on that end. I've run a pair of 145W in series but it would clip the power at 261W. Presently have a pair of 100W in series feeding 36-38V no problem charging 2 225Ah 6V batteries.

Would I be able to use this with a 280 watt panel to charge a 12 volt battery bank of 4 GC-2 6 volt batteries? Need to keep bank at 12volts to run bilge pumps: Grape Solar GS-P-280-Fab1 280-Watt Polycrystalline Solar Panel (Discontinued by Manufacturer)

I use mine with a 24 volt, 235 watt panel charging a 12 volt battery. It works great. I have seen the input voltage from my panel at over 30 volts -

Yes- I have connected a 240w panel (30V @ 8amps) and also two 135w panels (total 35V @ 3.8amps each) and it works fine. The limiting factor that may cause the confusion is that the maximum output is 240watts (12V @ 20amps) if you are connected to 12V batteries. In my case, I was connected to a 24V battery bank and was dumping about 17amps at 26volts into the batteries when I had all panels connected (the 240W + 2x130w). For the money the controller works well. If you connect to 12V battery; 240w is maximum; if you connect to 24v battery you can get 480w. It doesn't support over 32 volts, so you can't use a 48V battery bank. Yes- I have connected a 240w panel (30V @ 8amps) and also two 135w panels (total 35V @ 3.8amps each) and it works fine.

I bought two panels, have not installed them yet. Starting out with 4 batteries @ 100 amps, plan on going to 8 and adding two more panels

This panel is a 60 cell module (Vmp = 30.1v). You will need 2 x 250w in series to make close to ~60v output, and 4 x 250 in series to make close to ~120v output.

If you are asking how many panels it will handle I am using (1) 255 watt 33 volt module and it is rated max is 260 watt it is handling it great

This is why I hooked my 520 watts of panels in series so you halve the amperage. I can add another 2 panels in the future and still keep it under 30 amps. Remember too that the charge controller can charge a normal 12v battery bank, that's what mine is. I recommend making a 24v panel setup.

If you have an inverter it will work just fine. I have a 250W inverter and works well.

More important than the wattage for this system is the voltage. You need to make sure that your panel puts out a voltage that's in the range of this inverter. This inverter operates from 10.8-30v, so in low sun when you're below 10.8v it will not operate. Conversely, if your panel puts our 30v, you will be putting to many volts through this inverter in direct sunlight. Also remember that it is a 600w peak inverter, so if you put 3 200w panels on it, you're operating it at full peak efficiency. I try to keep my 600w inverters at 540w of panel or less. This increases efficiency and also extends the life of the inverter. When you do expand, you have to decide whether you will wire your panels in parallel (to double the wattage), or series (to double the voltage) If you want to wire in series, you need a bigger inverter, if wiring in parallel, you can only really safely put one more 200w panel on this inverter. Hope this helps.

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.

This unit is a 10 Amp charge controller. That means the maximum input wattage it can handle is 120 watts @ 12 vdc. Your 500 watt panel would exceed this unit's rating. After my unit didn't work I sent it back and purchased a Morning Star, which was made in the United States.

First, I bought one to keep a deep cycle battery charged up. Second, I would not use the 160 watt panels as they would not be cost effective (you would probably need lots).Instead look at the 250-300watt panels. As to the #, it depends on how much power you consume, and how much of that you want to generate, ie, 5-10KWH per day.

I see its states 12/24 volts.,100volts, woow that's a lot.,,yes Pv power refers to the solar panels as far as I understand.,i have a 12volt system.,with one 100Watt panel.,you have 24volts, so what are you confused about. you have another 76 volts to go before you could have problems.,,,LOL...Hope this helps.,we are all learning.,,

I don't think it will handle more 100watts.Be careful this unit is bad about running down the battery

I would connect up no more than 400 watts of panels. In my experience, these inverters are not conservatively rated. You are especially at risk when the sun first strikes the panels on a very cold day. Stay with 400 or less and you will be fine. I tried connecting (2) 280 watt panels and the inverter fried. This is fairly common. Check on Utube for similar experiences.

The HQRP charge controller will work with your 100 watt panel. Whether or not your entire "system" is right for your needs depends on your loads. If you plan on running a fridge, TV, radio, lots of lights, electric heater, etc., it ain't gonna happen.

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.

It is 250 W so the panel or panels should not deliver more. Just connect the panels to it and plug it in to your 120 VAC outlet. That is it. You can connect it thru a watt meter to see how much it is delivering.

Just because the panels are 100 w each dosen'T mean you will receive 100w all the time. 100w is the best you are going to get at top conditions. perfect alinment, perfect sky, alinement faceing sun all the day, so don't expect 100w all the time. There could be a haze between you and the sun,Wire size, conectors , if you are using it to charge batteries, Every thing can efect your wattage.
