5kw Sunforce 5kw Off-grid inverter Features:

Remote Monitoring
Check how your solar system is performing with remote monitoring the CubeWiFi/CubeGPRS accessory is great for understanding your energy consumption.

Parallel Option
Expandable by adding up to 6 units in parallel making this inverter more versatile than the more expensive brands such as the popular Goodwe that doesnt support parallel operations.

Completely Autonomous
Keep the lights on and your bills to zero with no effort. This solar 5kw inverter is smart by knowing what to do and when, it knows how much energy from each source there is and utilizes it accordingly.

System Connection
This is a multi-function machine, combining functions of 5kw inverter, MPPT solar charger and UPS module to offer uninterruptible power support with portable size. This inverter can work with or without batteries. With the CubeWiFi/CubeGPRS accessory, you can monitor the status anytime anywhere.

Inverter Features:
Configurable AC/ solar input priority via LCD setting
Compatible to mains voltage or generator power
WIFI/ GPRS remote monitoring
Configurable charging parameter, suitable all kinds of rechargeable battery
Parallel operation with up to 6 units
Can work with battery or without battery


Freedom Won 15/12 Lithium-ion battery features

This Freedom Won battery Lite Home LiFePO4 battery is the perfect high quality battery for all your residential and industrial solar solutions. The range is from 5KWh to 30KWh batteries.

Product Features
  • battery is compatible with most inverters on the market
  •  these batteries can be expanded by adding more batteries in parallel
  • 10 year warranty ( 4000 cycles) at 80% DOD
  • Battery Type: Lithium Ion
  • Nominal Energy:10000 W/h
  • Depth of discharge:90.00 %
  • Voltage:48 V
  • Maximum Charge Rate:10000 W
  • Maximum Discharge Rate:15000 W

The advantages of Li-ion technology mean that these batteries are finding an increasing number of applications, and as a result a huge amount of development is being invested into them.

The li-ion battery advantages include:

  • High energy density:   The high energy density is one of the chief advantages of lithium ion battery technology. With electronic equipment such as mobile phones needing to operate longer between charges while still consuming more power, there is always a need to batteries with a much higher energy density. In addition to this, there are many power applications from power tools to electric vehicles. The much higher power density offered by lithium ion batteries is a distinct advantage. Electric vehicles also need a battery technology that has a high energy density.
  • Self-discharge:   One issue with many rechargeable batteries is the self discharge rate. Lithium ion cells is that their rate of self-discharge is much lower than that of other rechargeable cells such as Ni-Cad and NiMH forms. It is typically around 5% in the first 4 hours after being charged but then falls to a figure of around 1 or 2% per month.
  • Low maintenance:   One major lithium ion battery advantage is that they do not require and maintenance to ensure their performance.

    Ni-Cad cells required a periodic discharge to ensure that they did not exhibit the memory effect. As this does not affect lithium ion cells, this process or other similar maintenance procedures are not required. Likewise lead acid cells require maintenance, some needing the battery acid to be topped up periodically.
