Do you have a question about the Pure Sine Wave and is the answer not in the manual?

My battery voltage is usually two volts higher than the reading on my 48 volt pure sine wave inverter. So when my battery is at 49 and 1/2 the inverter reads 47 and a half and starts beeping is there any way I can change this setting so that it draws the same amount that the batteries have in them

Summary of Contents for Mxmoonfree Pure Sine Wave

  • Page 3 Ⅰ. SAFETY FIRST The function of the inverter is to convert DC 12V/24V/48V into AC 110V. Mxmoonfree’s pure sine wave power inverter has adapted the SPWM technology which makes it highly efficient and reliable. Incorrect installation or misuse of the inverter may result in danger to the user or hazardous conditions.
  • Page 4 by a qualified, licensed electrician. CAUTION! Safety Instructions - Inverter Related Do not connect live AC power (City power/ Grid Electricity) to the inverter’s AC  outlets. The inverter will be damaged even if it is switched OFF. Preventing Reverse Polarity on the DC Input Side ...

    III. FRONT VIEW ①AC Outlets - 110V AC 60Hz. Maximum recommended output per outlet is 1500W. ②Power LED (Green) - When this green LED is lit, the inverter is operating. ③Fault LED (Red) - The red indicator turns on as the inverter shuts down due to overheating, overload, under voltage, or over voltage.

    National Electric Code (NEC) wiring gauge recommendations, 1000W excluded. Facing the front panel, the terminals are: Left Middle Right Neutral (N) Ground(G) Live(L) NEUTRAL and GROUND are bonded inside the inverter to comply with the National Electric Code (NEC) requirement that any AC source must have a neutral to ground connection.
  • Page 8: Status Indication

    DC to AC inverters require high amperage/low voltage DC power to low amperage/high voltage AC power. In order to reduce the risk of overheating due to DC side high currents, we set up second terminals on the same side (2 negative, 2 positive) and connect them in parallel.
  • Page 9 Short circuit protection: inverter is with short circuit protection.  Over-heat protection: when the inside temperature of the inverter reach 176 F (80  Celsius), the RED indication light will be on. The inverter will stop working, once the temperature drops to accepted level, the inverter will automatically resume working.
  • Page 10 Batteries used to start engines are not designed to repeatedly charge and discharge. Mxmoonfree recommends using "deep-cycle" or "marine" rated batteries. The following takes a 12V inverter as an example, the battery bank will be 12 volts...
  • Page 11: Installation

    VII. INSTALLATION Getting Started When a motorized appliance or a tool turns on, there is an initial surge of power to  start. This surge of power is referred to as the "starting load" or "peak load." Once started, the tool or appliance requires less power to operate. This is referred to as the "continuous load"...
  • Page 12: Battery Connection

    Battery Connection When connecting the inverter to the battery terminals, it is important to connect  the "+" wire to the "+" terminal and the "-" wire to the "-" terminal. Do NOT reverse the polarity. It will void the warranty. Make sure you connect negative to negative and positive to positive.
  • Page 13: Operation

    DO NOT allow the wires to cross or touch each other. Install the cables facing away  from each other and screw tightly. When connecting the battery cables to the terminals of the inverter, make sure they do not touch the case. Loose connections can result in a severe decrease in voltage that can cause damage ...
