Wavetra 3kVA Inverter Charger (2 In 1) MPPT 60A solar charge controller


Wavetra 3024 inverter charger is a combination of an inverter, battery charger and transfer switch into one complete system. When AC power is available, the inverter/charger recharges the house batteries. It also allows any surplus AC power to pass through and power downstream AC loads, such as a television set or microwave oven. When AC power is disconnected, the unit inverts DC battery power into AC electricity. Wavetra 3024 Watt Pure Sine Low-Frequency Inverter split phase with built-in battery charger and transfer switch.

This inverter charger is perfect for medium-sized industrial applications that depend upon power being available even under heavy load. This heavy-duty inverter charger is ready to go wherever you need it. Use this product for renewable solar, off-grid, business back up power, mobile and emergency backup power applications anywhere that uses 100/110/120/220/230/240 volts of alternating current.

This product also has auto frequency detection that allows users to operate at either 50 or 60 Hertz. This inverter charger includes a powerful 55 amp charger and is capable of accepting any source of 240V AC power to charge batteries, including a gas or diesel generator or shore power. The 3000-watt inverter charger is capable of a 5000-watt surge for 5 seconds and can run at 4000 watts continuously. This inverter will never completely drain your batteries as it’s low-voltage shut-down keeps the voltage at either 20 volts or 21 volts depending on your selection. With the battery priority mode, you can set your inverter to run directly off of a battery back-up system instead of a generator or tertiary source of AC Power.

The inverter-charger comes with a power saver mode that pulses every 30 seconds, attempting to detect a necessary load of 25 watts or more before it will turn on. Otherwise, the inverter will “sleep” and draw right around a half an amp per hour, saving you precious reserve power in your batteries until you need it. An optional wired LED or LCD remote can be added for fast and easy operation if your inverter charger is mounted in a location that is inconvenient to get at.

This allows the unit to be operated within the cab of a vehicle or from another location in the home or campsite.


◆ It applies all-digital voltage and current double closed-loop control and advanced SPWM technology, available in two output modes i.e. pure sine wave output, and Utility bypass, and an inverter output, thereby providing uninterrupted power supply.

◆ Four charging modes are optional, i.e. Solar Only, Utility Priority, Solar Priority, and Utility & Solar charging. Maximum power point tracking (MPPT) technology ensures a tracking efficiency of not less than 99.5%.

◆ The LCD with an easy-to-understand operation interface presents a dynamic display of system operating data and working status. 3 LED indicators indicate the working status of the system at all time.

◆ The ON/OFF rocker switch button allows for independent control of AC output, reducing unnecessary losses, without affecting battery charging by PV or utility power.

◆ Intelligent speed variable fan control maximizes fan life while addressing the internal heat dissipation of the machine.

◆ PV can activate the lithium battery, and additionally, the Utility supply can activate the auxiliary power supply of the machine to ensure that the Utility can charge the battery in time under the condition of the battery under voltage loss. When only PV is connected with no battery input, the maximum load can be half of the rated power.

◆ Improve protections for all kinds of abnormal conditions to ensure that the machine will not be damaged due to improper wiring and loading.
