Solar Inverter technical detaitls

Load Sharing Function.

Multiple Power Modes.

Completely off grid, no utility power, Solar power supply power to home directly, call it line mode power. solar DC --> AC 230V directly.  Excessive solar power charge battery to store solar energy.

Completely off grid, no utility power. Solar power is not enough for electric appliances. so the extra power supplied from battery. when solar power supply 90%, then battery give extra 10%.   if solar power give 50%,  then battery give extra 50%.   If solar power only 20%, then battery give 80%.  etc.  night time, solar power gone. power source 100% from battery
Off grid hybrid working mode, solar panels and utility power source, both available, 2 power source supply to home electric appliances. when solar give 90% power, utility give 10%.  when solar give 50%, utility give extra 50%.   when solar give 10%, utility give extra 90%, etc.  solar power also charge battery.
solar power is not available, like night time, or no solar panels installed. utility is the only power soure,  utility supplys power to electric appliances, also charge battery to store energy.

No solar power, no utility power,  battery is the only power source.

2 ways to control solar inverter settings

* Real-time monitor power data

* Remote control solar inverter

Conformal Coating Processing

Protect inverter from dust and humidity corrosion, increase solar inverter life-span

3 protections:

1: Over load Protection

2: Short Circuit Protection

3: Over Temperature Protection

4: Fuse,  5 Circuit braeker

FAQ

1: What is the difference between PWM inverter and MPPT inverter

Answer: PWM is Pulse width modulation, it is a old solar power controller technology,  its efficiency is about 70%

MPPT is Maximum Power Point Tracking, it is the latest technology. it contains Low Voltage and High Voltage, 2 types.   High voltage inverter efficiency up to 95%

2: How to distinguish Low voltage and high voltage inverter

Answer : Low voltage, Max PV voltage Voc < 150V.    High voltage, Max PV voltage Voc > 450V

3: Sometimes products description writes MPPT inverter 3000W and MPPT 4KW,  it is confusing,

why write 3000W and 4000W , is it contradictious

Answer :  3000W means inverter support Max load 3000W, (TV, laptop, airconditioner, fridge etc).

MPPT 4KW is MPPT controller, it can abstract 4000W power from solar panel,  supply power to appliances and supply power to battery at the same time. Battery charge power +  Load,  together up to 4000W

4: During day time,  power supply to load,  does it come from battery to solar power.

Day time there is enough solar power,  Appliance powered directly by solar power,  and battery get fully charged and stand-by mode.   Night time solar power gone, Battery get activated and start to supply power to appliances

Or during cloudy day, solar power is weak and not enough, battery work as auxiliary power.

5: Do you accept OEM / ODM

YES, we accept OEM/ODM. We have our own technician team, we have 15 years in product development and circuit designing. Earlier we provided only solar inverter design and solution service to trading company. Now we start to sell completed products. So we provide ODM , For details we will evaluate based on customer requirement.

6: If we want to print our company Logo on products, how many pcs as MOQ to start.

YES, we do laser Logo print for customer,  MOQ starts from 10pcs,  customer need to pay for the extra logo print cost.    If customer order accumulately up to 100 units, we refund logo print fee
