Modified Sine Wave Inverter:

Modified sine wave inverter, or quasi-sine wave inverter, works with most of standard appliances. Based on simple but older technology, typical modified sine wave inverter can be applied to simple power system without any delicate electronics or audio equipment. In some cases, your equipment may run hotter with modified sine wave inverter, which may also bring out potential in damaging your device in a long run.

Pure Sine Wave Inverter:

Compared to modified sine wave inverter, pure sine wave inverter produces much more efficient power and far less interference ensuring your equipment to work at its full capacity. Pure sine wave inverter is generally preferred for sensitive electronics that require more efficient power and protection, while offers great versatility than modified sine wave model.

Pure sine wave has the following advantages compared to modified sine wave in applications:

b) Pure sine wave ensures inductive loads in electronics to run quieter, faster, cooler, and smoother.

c) Pure sine wave helps in reducing humming noise or buzz when using electronics such as fluorescent lights, game consoles, TV, and fans.

d) Pure sine wave works in preventing crashes in computers, and eliminating noise, glitches, or indistinct printout in monitors.

Leaptrend inverter(link) has a remote ON/OFF switch. To run your device on a schedule, you can turn the remote switch on then test if it works with a computer-controlled relay(timer).

Our current model of inverter can only work with 12V battery system.

1.Firstly, Size the Right Power Output.
Inverters will be rated by a wattage value. According to this code, if there were 1000 Watt air conditioning and 800 Watt fridge; These electronics would be counted as 1800 Watts then require an inverter over 1800W. In this case, Leaptrend 2000W and 3000W inverters can perfectly cover your power needs.

2.Secondly, Check your Battery Voltage.
The next step is to check the DC voltage rating of the inverter for a compatible battery bank. The voltage rating information is on the inverter, while you can also handily check the specification section on the relating product page at leaptrend.com for more detail. For example, an inverter with 12V DC input can works with a 12V battery bank.

3.Thirdly, Keep a Mind on the Installation Space.
Sizing the place where you design to install the inverter, and checking for good ventilation and no fire hazards.

Yes. If the input voltage drops to 10 volts, the automatic shut down will be activated to protect the battery.

The DC to DC battery charger(link) is functional to charge batteries using the power of your generator or vehicle's alternator. When you are driving, you can use the charger to charge your off-grid battery (as secondary battery or house battery) with your operating battery (as primary battery or starter battery) connected to the generator/alternator. To put it short, you can charge both batteries while driving. That is why the charger is commonly installed between the generator/alternator and both starter battery & the house battery on the system. In a regular RV system, the generator/alternator ensures stable power supply to the starter battery, and the charger helps to use excess DC power from generator to supply the house battery through the starer battery.

Make sure it is a 12V battery system. The maximum charging current provided by the DC to DC battery charger does not exceed the current allowed by the house battery (as secondary battery).

Leaptrend 12V DC to DC charger works in supply voltage from 8V to 16V. The charger will charge battery during the range, while please be aware that the lower the supply voltage, the higher the amperage required to maintain the function.

Yes, there is a terminal on our charger to connect an ignition wire. It will have a steady output regardless of the fluctuations in the input voltage.

When you are driving, your RV alternator is charging your starter battery, and the alternator itself is also charging your house batteries along with the starter battery. To charge the house battery without connecting to the starer battery, you can install the charger then wire it into the starter battery. After the installation, you can place the third wire going to the ignition. By this method, it will work but only when the vehicle is running.
