This only handles 390 watt of solar power at 12v?
616965
Yes if you have solar panels that put out as much as 32 amps controller. 12v x 32a =390 watt. This is a pretty big system.

The spec sheet rates the Tracer-3215RN for use on 12 or 24 volt systems. Max input from the PV unit is 150VDC @30 amps. Presently I am inputting 30 volts from my panel array @34 amps which is @ 1020 watts and I have been doing this for several months. My storage bank consists of 18 marine batteries at 12vdc. I have been doing this for several months and all works quite well. Hope that helps.

lets say you have 6 - 100watt panels (20 volts and 5 amps). if you connect 3 sets of 2 panels in series then connect the sets in parallel - you would have 40 volts and 30 amps. Depending on your efficency of your panel you could exceed the specs some of the time. If a working controller really matters to you then you might not want to find out what happens when exceeding specs. But using a combination of series and parallel you could stay within specs. Just remember that a series connection will degrade to the lowest panel. You may want to have the Remote Meter LCD Display (MT5) for Solar Regulator with 2 Meters Cable to monitor your system.

Their book specifies Max PV input power 12V/390W or 24V/780W. My PV output is max 18V at 21A. That is 378W (18 x 21 = 378) and does not exceeded their specs so I don't have any experience as far as exceeding the books specs. Going from a 12V to a 24V PV system will double your wattage without increasing your amperage however, in order to use that increased wattage without exceeding the 30A output current, you would also need to change to a 24V battery system. The output is rated at 30A regardless of the input voltage or amperage or battery voltage.

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.

I fried a couple experimenting with voltages above 12V. The circuitry got very hot and failed. The lower voltages can be accommodated with the calibration pod. I have successfully powered it with a small solar panel with power ranges all over the board on cloudy days.

145watts *2 panels is 290watts --- 290watts / 12volts = 24.16amps under max sunlight and optimal conditions. Youll need to use 2 charge controllers or one that can handle 48.34amp. 2 charge controllers will work together to get the batteries charged. I currently am useing 3 with my 840watts and get about 70amps to charge 9 115amp/hr batteries.

The capacity is 400W at 12V and 800W at 24V, so you can use one panel at 12V and up to three on 24V.Thank you for your interest.GordonGLR Industries, LLC

If I understand your question correctly. your requirement is for a 400 watts solar input and if 408 watts of solar input is ok, I am assuming your question is for an off grid system (charging batteries). Question is if your your charge controller can accommodate additional 8 watts of input or ignore this additional watts without damaging any of the equipment. Please check the documentation of your equipment (charge controller) if it will work properly with the additional power provided by the solar panels. Normally additional power provided by the solar panels is ignored, one should make sure that electrical specs are matched with the solar input with the charger such as input voltage 24v panel and 24v charge controller input. Output from the charge controller should be matched with the battery voltage such as 24v solar panel, 24v charger and 24v battery, if different use an MPPT charge controller which can accept higher voltage from the solar panel and charge a lower voltage battery such as 24v panel, MPPT charge controller and 12v battery. Hope I have answered the question.

No! Its not enough watts for what you need it for. 800watts - 300watts = 500watts

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.

If you have 500 watts of solar collecting capacity my understanding is that it would exceed the capacity of this controller. I recommend getting a 40amp MPPT controller. I got this controller for testing purposes but even my two panels rated at max 140watts each would exceed the capacity of this charge controller in full sun.

I suggest you buy a converter which supports power at least 3 times larger than what you really need, this will make you less trouble. Thus for your PS, 500W seems good enough.

This is compatible with a 12volt system as with any solar panel you will require other parts to macke this work saflely and efficiently as a renewable energy system Hope this info helps you Joe

I'm using this controller to charge a bank of 4 12 volt batteries and my solar panel is rated at 30 watts and 17.5 volts. It seems to be working fine but I don't know if the controller lists any maximum input voltage or not. One would think it would be capable of handling a wide range of voltage just because of the nature of most solar panels but that is simple logic and simple logic doesn't always apply.

I think you will be OK. If you do the math, 6X200 = 1200 watts. That's easily handled by wattsup. Be careful to connect the solar cells to the "source" end, also I would use a diode to prevent any chance of backflow, just as a safety feature.

Yes, but remember, the thing supplying the power must be a high power device as well. Meaning your 12V socket as well.

There is only one 12v rail, but it can handle 540w - just shy of the total output. Unless you're really pushing the total capacity (which you shouldn't do), it shouldn't make an important difference.

You can use this controller for 12v but there will be power clipping. The best controller would be the Outback FM-80 for 1KW solar panels charging a 12v battery bank. Thanks, ML SOLAR

Check the power rating on the spec sheet. I've got a 650watt and its been fine.

Hey Edwars O. Not sure. What type/sort of system are you putting together? 6V 12V? What are you needing to run, and for how long? What are your energy needs? I can't answer your question my friend without more info. I personally use the 400 watt system with another 100 watt panel. I match my batt bank so every 100 watt of solar for 100Ah of storage. Yes, it is over kill for just myself! I'm still in the learning processes if you will. The panels that come with this kit have zero issues with charging the batteries on cloudy days. I'm very happy with this basic system so far!!
