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:Three-phase photovoltaic inverter grid, the use of phase-locked loop is what?
In addition to the function of converting DC current into alternating current, the inverter also has the maximum output tracking function (MPPT), overvoltage protection, short circuit protection, island protection, overheat protection, overload protection and DC grounding
Q:PV grid-connected inverter can directly load it?
Grid-connected inverter is like a car file, he first detects the grid waveform, can not detect not boot, and then the PV DC modulation and consistent with the grid waveform, and then hang up.
Q:Solar grid inverter does not merge into the grid, direct access to the load to the load power supply?
The solar grid-connected inverter is not connected to the grid and can not be directly connected to the load to supply power to the load because there is no voltage.
Q:PV grid-connected inverter and independent inverter in the control of what is the difference
The independent inverter in the output voltage phase amplitude of the frequency control is initially set good. Independent inverter, you should refer to off-grid inverter, do not need to consider the grid situation.
Q:What is the difference between a PV inverter and a solar inverter?
The main component of the inverter is the three-phase bridge converter. The main purpose of the grid-connected inverter is to change the power to DC and change the AC power. The main purpose is to improve the power quality (because the wind power generation is very large
Q:What are the methods of photovoltaic grid-connected inverter control
and can set the dead time between the upper and lower arms, the use of INTEL 80C196MC to achieve sine wave output circuit, 80C196MC to complete the sine wave signal, AC output voltage, to achieve regulation. Circuit output generally use LC circuit filter high frequency wave, get pure sine wave.
Q:The function of photovoltaic grid - connected inverter
By dc / dc conversion to increase or decrease the input voltage, adjust its output to achieve maximum efficiency.
Q:What is the difference between a PV grid-connected inverter and an off-grid inverter?
Off-grid inverter is equivalent to their own to establish an independent small power grid, mainly to control their own voltage, is a voltage source.
Q:Generally a large grid-connected photovoltaic power plant will have several inverters
, This method is simple to design, easy maintenance, but also for the power grid harmonics smaller, good power quality!
Q:What is the difference between a grid-connected inverter and an off-grid inverter? What are the advantages of a hybrid inverter?
Grid-connected inverter does not need energy storage, but the energy can not be controlled, how much light to send online to the number of online, simply do not want people to the grid does not like.
