Meet the IESS-1K20N.
Power Tank 1000 brings three essential parts of a household energy system into one unit: a 1000W pure sine wave inverter, a 2000Wh LiFePO4 battery and a solar controller that supports up to 1200W PV input. There is more output for compatible equipment and more stored energy for the same everyday load.
Its 1000W output supports compatible essential equipment while the 2000Wh battery provides a useful reserve for longer evenings and working days.
What can the 1000W model power?
Televisions, laptops, routers, LED lighting, phones, POS devices and compatible office or security equipment can be useful loads. Add together the ratings of the devices you want to run at once and keep their total within 1000W.
Fridges and freezers need a separate check because starting a compressor can require more power than keeping it running. Send your equipment details to Mr. Olamide and we’ll help you choose.
How long will it last?
The 2000Wh battery gives you stored energy for everyday backup. Using 85% of nominal storage, a steady 200W setup calculates to about 8.5 hours; a 400W setup calculates to about 4.3 hours. Actual runtime depends on battery condition, appliance use and conversion losses.

The IESS-1K20N supports AC charging and compatible solar charging. Its published PV limit is 1200W, with a 60V maximum PV voltage and an 11–60V MPPT operating range. Match the panel voltage, current, connectors and cabling to the manual before connecting a solar array.
Published product information describes approximately two-hour charging with an appropriate setup. Available input, battery level and conditions affect recharge time.
