ACOPOWER PWM20A, Product Introduction

3×40W

●Lead acid, Lead crystal, Lithiumion, LiFePO4, LTO batteries can be dangerous. Ensure no sparks 

or flames are present when working near batteries.Refer to battery manufactures specific 

recommended values for battery type and charging rate setting.Do not charge to an improper type of 

battery. (For example, do not charge Gel battery with Calcium battery setting) 

●Never attempt to charge adamagedbatteryor frozen batteryor non-rechargeablebattery. 

● Never smoke, use an open flame,or create sparks near battery or solar controller during charging 

operation as batteries may give out explosive gas. 

●Eye protection should always be used. Never short circuit the battery. 

●Someone should be within range of your voice or close enough to come to your aid when you work 

neara lead-acid battery or Lithium ion battery. 

●If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye, 

immediately flush eye with running cold water for at least 10 minutes and get medical attention 

immediately. 

●To reduce risk; avoid dropping a metal tool onto the battery. 

●Given sufficient light solar panels always generate energy even when they are disconnected. 

●Accidental ‘shorting’ of the terminals or wiring can result in sparks causing personal injury or a fire 

hazard. We recommend that you cover up the panel(s) with some sort of soft cloth, so you can block 

all incoming light during the installation. This will ensure that no damage is caused to the Solar 

Panel or Battery if the wires are accidentally short circuited.

●Always install a battery fuse on each circuit including the solar controller 

● Do not disassemble charger,take it to a qualified person when repair is required. 

● Do not reverse connect the wires to the solar panelor battery 

●Appliances incorporating batteries which contain materials hazardous to the environment.
