Solutions for Off Grid System

off-grid inverter solution

Can partially or completely replace diesel generator.System Capacity: 3-50kW

  • *Off-grid system is a good solution for the area where is no electricity, shortcomings or with unstable power.
  • *Advantage of photovoltaic power:
  •         * economic
  •         * clean
  •         * environmentally friendly
  •         * noise-free

Off-grid Inverter two Working Modes

off-grid inverter work modes

SNA5k serial off-grid inverters can support the system to work as back-up power or a replacement for a diesel generator. Since the inverter support paralleling function, the capacity of the system can range from 3kW to 50kW, The inverter support several working modes.

Pure off-grid working mode: working as traditional off-grid inverters, can set the output to utility first, battery first, or solar first.

Hybrid working mode: working as a hybrid, support solar and utility jointly take the load, can set to the self-consumption mode or charge priority mode.

Off-grid Inverter 4 Features

1.Features--Wireless Paralleling Function

10pcs or even more paralleling extend to 50kW VS 6/9 pcs paralleling max
Can connect battery as one big group bank or seperately battery group; Keep same SOC for groups Can only connect to one big battery bank
Do not require inverters to battery same cable length Require inverters to battery same cable length
No current share cable, same esay communication cable connection With current share cable, different cable connection for different system

2.Features--Grid/Battery/PV Jointly Take the Load

For traditional off grid inverter, load was taken either by battery/PV or by AC grid , which will make low usage of solar power VS For Sonar Off grid inverter, you can use PV and utility take load and keep battery full  at the same time

 

3.Features--Independent Generator Input

* Independent generator input, free of ATS outside

* Flexiable control of generator

  •        Battery level/battery voltage can be set to turn on the generator
  •        Battery level/battery voltage can be set to turn off the generator
generator

4. Features--Battery Management

* Support Pylon/Weco/Dyness/Aoboet Li-ion battery

* One cable connection, do not need any external box for Li-ion battery communication

* Support battery equalization function to activate the battery period

* Support Battery wake up function

 

Monitor System Performance

monitoring system

* Multi-level management: Administrator-->Three levels of distributors-->Installer-->Enduser

* Easier to use(Register, set wifi password), only three steps 

* Local connection support

* Remote monitor, setting, and firmware update.Support Web/IOS/Andriod
