High Frequency Solar Inverter

PV1800 VPK Series High Frequency Off Grid Solar Inverter (1-5KW)

PV1800 VPK is a multi-function inverter/charger, combining functions of inverter, PWM solar charger and battery charger to offer uninterruptible power support with portable size. Its comprehensive LCD display offers user-configurable easy-accessible button operation such as battery charging current, AC/solar charger priority, and acceptable input voltage based on different applications.


  • Pure sine wave output
  • Smart LCD setting(Working modes, Charge Current, Charge Voltage, etc.)
  • Built-in PWM 50A/60A solar charge controller
  • New SUB working mode(Solar-Utility-Battery working mode) for 4K-5K series
  • Combining solar system, AC utility, and battery power source to supply continuous power
  • Overload, short circuit and deep discharge protection
  • Parallel operation with up to 3 units (Available for 4KW/5KW only)
  • Cold start function
  • Support USB, RS485 monitoring function with free CD
  • WIFI remote monitoring (optional)
  • Compatible to generator

Three Colors Option:


Pure Sine Wave Output

The electrical waveform output of PV1800PK is a pure sine wave, which has the same quality as utility and/or domestic power. This type of waveform is suitable for most all electrical devices, appliances and tools. This pure sine wave unit provides more capabilities than modified sine wave inverters, because it is a cleaner form of power. The pure sine wave also effectively reduces the noise produced while using appliances.

Wifi communication

you can download this app on your cellphone and monitor the whole system, you will know how much electricity the system generate and sell to utility.

Ability for parallel operation

The inverter is able to run in parallel operation mode to increase the capacity and reliability of the solar system. For higher reliability, parallel kits are adopted for invertersto communicate with each other. Up to 3 inverters can be installed together. Either single-phase or three phases parallel operation is available.

Charging algorithm

3-Step (Flooded Battery, AGM/Gel/Lithium Battery),4-Step(LI)

Monitoring system

With USB can connect with computer monitoring the working stage and the data of PV, AC and battery. LCD setting is also available in computer.

Utility-Tie state

PV energy is charger into the battery and utility provide power to the AC load

Charge state

PV energy and grid can charge batteries.

Bypass state

Error are caused by inside circuit error orexternal reasons such as over temperature,output short circuited and so on.

Off-Grid state

The inverter will provide output powerfrom battery and PV power
