powmr 30a solar charge controller, solar panel charge controller 12v 24v dual usb, adjustable parameter backlight lcd display and timer setting on/off hours(z30a) powmr <b>our advantages:</b><br><br>1.this solar power regulator protected with the moisture-tight coating, minimizing damage from humidity and from nesting insects. <br>2.dual usb place at both ends of the terminal.it will be better than dual usb in the same place for dissipate heating,prolong the controller life.supply power to two mobile phones, tablet pcs, and other devices that require 5v power. <br><br><b>specifications:</b><br><br>*max charge and discharge current:30a<br>*max input power and voltage:360w/23v(12v)<br>*usb output:dual usb output,5v/2.5a(max)<br>*equalization:14.4v<br>*float charge:13.7v(default,adjustable)<br>*discharge stop:10.7v(default,adjustable)<br> *discharge reconnect:12.6v(default,adjustable)<br>*charge reconnect:13v<br>*size/weight: 5.86*2.87*1.3in/0.44lb<br>x2all green color voltage x2 while using 24v system<br><br><b>safety instructions:</b><br><br>1. when installing for the first time, please make sure the battery has sufficient voltage so that the charger controller can recognize the normal battery type and system.<br>2.make sure the input power and voltage don’t exceed 360w/23v(12v battery) and 720w/46v(24v battery).<br>3. install the charger controller to the battery as close as possible to avoid voltage and power dropping caused by overlong wire and affect normal voltage judgment.<br> 4. charge controller should connect the battery first, and then connect the solar panel, and finally the load! the disassembly sequence is contrary to the wiring order<br>5.connect the inverter (dc / ac) to the battery. do not connect to the solar controller.<br>6.the lcd display has an error of 0.2 v- 0.3 v, but this is normal<br>7.the controller will stop output when the battery under 10.7v(adjustable).and it will re-output when the battery up to the 12.6v(adjustable)..<br>8.do not open the heat sink of the solar controller without permission.<br><br><b>package includes: </b><br><br>1.1 x 30a solar charge controller<br>2.1x english user manual
