2400w smart solar controller DC12V/24V, MPPT,100AMP, solar panel/3.5"LCD
LCD DISPLAY SOLAR OFF/ BTY (this page will clear show you the solar connecting SOLAR ON/ BTY (can clear tell you the solar is correct to connect & battery is on SOLAR : (will show you how many solar panel coming VOLTAGE: (will show you the voltage for your solar panel, laoding : (will show you how many amp coming into the : (will show you battery voltage)
Capacity : (this you need enter your battery size by your self)
Charge tme/F : (charge time for full, tell you how long your battery can be total energy: xxx KWH
total cost : $ xxx
SET BTY: setting your battery size
SET ETC: setting electricity bill
SET DEL: delete all your total energy & cost.

BIG LCD DISPLAY: 3.5" LCD(apple mobile phone 3.8", other controller 1.5")
The above controller we call smart controller, all the situations you can see it by your eyes very clear,
a lot customer use controller, but you dont know real watt & amp, you need to use amp tester to get the amp,
that's real not convenience, what this controller let you know your solar panel, battery situations with 3.5LCD
display, that's big, you dont need take off your glass to see, so with this smart controller, you will real understand
how your solar bring you the power!
Big cooling fan(before buying, check if other brand has cooling or not)
About 100a controller, this is industrail design, because we have coolling fan on it, let me tell why this need cooling on it,
because this is PWM design, means will make your solar from dc to ac to charge your battery, in this moment, it through
mos-fet to do this job, if your mosfet getting so hot, will effect the efficiency.
Inside mosfet we use made in USA 2times bigger than the 50a mos, can go to 95% efficiency, means if 100w solar coming,
you will get 95watt output, so controller is very important, if one hour you have 5watt different, then one day you may have 120w
different, how about year different, so we using inverter technology to design the controller, that would be the best choice when
you need the controller, tks.
MPPT+PWM+ON LINE GRID TECHNOLOGY(95-97%EFFEICIENCY)
Also this is MPPT technology, this is not usuall MPPT for other supplier, we use grid tie inverter technology to catch best voltage & amp,
other supplier mentioned when 17v-18v, will start to have amp coming, that's impossible, because your solar can not always keep 18v,
if keep so high like this, once the solar can not match, it will stop to put amp, until the voltage come 18v again.
so best voltage is keep 14-15v, but it's always keep stable amp coming, after a whole day total engergy will be better than the high voltage mppt.
as we are the on grdi inverter supplier about 5years, that's why we still offer same technology into the solar controller.
other supplier mppt controller, they put a choke & re-sort out the power, then charge the battery, ya, this is good idea, but after we make some testing,
we found no need to re sort out, as during this operation, you will lose 3-4% power, not necessary to waste your green power, so even you get more
power from your solar panel, but you need also think about the efficiency for the solar controller input & output, i am real sorry to talk about so details
like this, but as we are the green power supplier, that's our responsibility to tell you the know how, let me tell how important is this issue:
if you are using 1000w solar panel input, you have 3% different for 1hour, 1000w x3%=30watt 1day 24hours, 30w x 24hours=720w for one day,
one month is 30days, 720w x 30days=21600watt for month, whole year is 12months, 21600watt x 12=259,200, solar panel can use 20years,
259,200 x 20years=5,184,000watt.
so that's your choice when you purchasing your solar controller!
