SET BTY: setting your battery size SET ETC: setting electricity bill SET DEL: delete all your total energy & cost. G. Warming! your solar panel is over voltage H. Warming! your battery is low voltageSpecification:Systerm current 100A Voltage 12V/24V No load losses <5mA Charging circuit voltage drop Less than or equal to 0.20V Discharge circuit voltage drop Less than or equal to 0.15V Over voltage protection 19V/38V boost charge voltage 14v/29.2v Direct charge voltage 14.4v/28.8v Float charge voltage 13.5v/27.2v Charge recover voltage 13.2v/26.4v Over discharge recover voltage 12.5v/25v Lower voltage indication 12v/24v Over discharge voltage 11.1v/22.2vBIG 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!Warranty :Please check the carton and product after you receive the good, if something damaged during transportation by Express Company, let us know immediately, then take photos of the carton and product first(including the shipping label that shows the tracking number on it), then send the photos to us, and also test the product to see it works or not ,any problem pls contact us asap so that you can cover the corresponding warranty.Return / Replacement :Within 14 days(based on the delivery data) :Repair fee all free.

2. 2 big main board & 1 big transformer inside, original design is 4pcs middle transformer inside, now only 1pc, make sure with better efficiency.
3. easy to replace the parts, because with big space, all you need to do is turn on the box with key, friendly space to let you manual to replace the main board or control board.
20171025Q: About the LF inverter, you have small metal on/off switch? Why you need this button?
A: Yes, this is marketing response, as some freezer & refrigerator, when you turn it on this appliance, will need big amp in the first begining, the transformer inside will get hot in the mini secs, so the sensor not faster enough to turn the fan on, so sometimes the fan not turn on the inverter shut down because the high faster hot coming, in this moment, you better put the manaual switch for the fan to come down the teamp, that's why we make this special design, tks.
20171027Q: what is no load current for 3000w LF inverter 12v?
