Product Description:

Pure Sine Wave Inverter EP2000 Series 300W/400W with LED Indication, Single Phase


This high efficiency microprocessor controlled DC-AC inverter converts 12 Volts DC (Nominal) 300/400Watts of pure sine-wave AC power at 100/120/220/230 Volts, 50/60 Hz.

The unit comes with in-built 7 Amp transfer switch and a 20 Amp circuit breaker.

Input battery cable lugs are provided and the AC output is obtained through hardwire connection.
Features include overload, short circuit, over-temperature, under & over voltage protections, and selectable. emergency home backup.

Safe to use and features over-current, over- temperature and surge protection.

Simply connect the inverter to a battery and plug your AC devices into it, then you’ve got portable power.



Can be used with different domestic appliance TV, Refrigerator ,Fan , air conditioner ,induction cooker , micro-wave oven etc .

provides a 1~3 year limited warranty (“Warranty”) against defects in materials and workmanship for its Uninterruptible power supply, Power inverter/chargers, Solar charge controllers, Battery Products (“Product”).

The term of this Warranty begins on the Product(s) initial purchase date, or the date of receipt of the Product(s) by the end user, whichever is later. This must be indicated on the invoice, bill of sale, and/or warranty registration card submitted to MUST-Solar. This Warranty applies to the original MUST-Solar Product purchaser, and is transferable only if the Product remains installed in the original use location.



1.    How do I decide which system is right for me ?

For protection from long outages, include a generator or solar panels in your Must solar system. Shorter outages can be handled by a battery-only system.

2.    Where my system will be installed ?

Must solar systems are usually wall-mounted near a home's main electrical (circuit breaker) panel.

3. How do I install my system ?

A must solar backup inverter is connected to a home electric system , we will supply detailed installation manual and videos for our customers .

Q:Solar grid inverter does not merge into the grid, direct access to the load to the load power supply?
In foreign countries due to the higher penetration rate of the car to go out to work or travel can be connected with the inverter battery drive electrical and various tools work.
Q:Three-phase photovoltaic inverter grid, the use of phase-locked loop is what?
Photovoltaic inverters for grid-connected photovoltaic power generation systems are primarily capable of receiving DC power from photovoltaic arrays and converting them into sine-wave currents of the same frequency and in phase with the access grid for powering the grid or local loads.
Q:What are the methods of photovoltaic grid-connected inverter control
The square wave output of the inverter using pulse width modulation integrated circuits, such as SG3525, TL494 and so on. Practice has proved that the use of SG3525 integrated circuits, and the use of power FET as a switching power components, to achieve high performance of the inverter, because the SG3525 has a direct drive power FET capability and has an internal reference source and operational amplifiers and Undervoltage protection, so its peripheral circuit is very simple.
Q:PV grid-connected inverter can directly load it?
TL5001 operating voltage range of 3.6 ~ 40V, its internal with an error amplifier, a regulator, oscillator, a dead zone control PWM generator, low voltage protection circuit and short circuit protection circuit
Q:What is the difference between a PV grid-connected inverter and an off-grid inverter?
Offline generally need energy storage, not to send energy online. Power grid has no right to interfere.
Q:Photovoltaic grid-connected inverter problem
The first zero line is the AC output. Any AC output of the inverter will have zero line, whether it is isolated or non-isolated. Isolation is the safety of high voltage inverters and regulators. 50KW above the inverter almost with the transformer.
Q:What is the difference between a PV inverter and a solar inverter?
Instability, the wind speed and the equipment itself will directly affect the generator rotation, so the voltage and current fluctuations, frequency instability, in short, is the power quality is poor) Therefore, through the inverter after the first rectification inverter to improve the quality of power
Q:Is the PV inverter a current source or a voltage source?
According to the waveform modulation method can be divided into square wave inverter, stepped wave inverter, sine wave inverter and modular three-phase inverter.
Q:Is the grid side of the grid and the inverter?
Off-grid system power transmission sequence: photovoltaic panels> relays> inverters> relays> electricity load;
Q:Generally a large grid-connected photovoltaic power plant will have several inverters
The use of a high-power grid-connected inverter into the grid, the need for line design is relatively simple, because the DC and AC lines are separated, the use of convergence box to summarize, DC bus and then into the grid inverter
