Lithium ion batteries have the advantage over traditional lead acid in that they can be cycled many times more and can be discharged deeper while maintining a decent battery life.

The Pylontech batteries in this kit are one of the best sellling lithium ion batteries in South Africa, and if you register your purchase with Pylontech, you can get a 10 year manufacturers warranty for no additional charge.

This Kit Includes:

  • 1 x Axpert Voltronics VMIII Inverter (Invermax branded)
  • 1 x Battery Pylon Cable Pack
  • 2 x Pylon battery brackets
  • 2 x Pylontech Pylon US2000 2.4kwh Li-ion Battery – 3.8kWh usable
  • 1 x KETO 80A dual fuse disconnector

For those not overly familiar with electrical power, this systemcan store around 3.8 Units of electricity in the batteries.

This means that at during a power failure, you could watch a 300W TV for about 10 hours before the batteries went flat (300W x 12 hours = 3600Whrs = 3.6 Units of electricity)


you could run 40 x 5W LED globes for 15 hours (5W x 40 x18 hours = 3600Whrs = 3.6 Units of electricity)


a 1200W kettle for an 3 hours straight (1200W * 3 hour = 3600Whrs = 3.6 Units of electricity) *Not sure why you would do that but who knows?*


any combination of the above that adds up to 3.8 Units.

The system will switch from grid power to battery power automatically upon grid failure and automatically back to grid when power returns. The batteries will then automatically recharge.
