Introducing the ElektroBank Battery Storage + Solar Hybrid Inverter System

The ElektroBank is a breakthrough lithium iron phosphate (LiFePO4) battery, hybrid solar PV inverter, water-heater controller and grid integrated device designed to maximise value and return on investment.

The ElektroBank’s all-in-one design delivers Australia’s most reliable, lowest cost per warranted kWh solar storage system. It automatically adjusts battery charging and discharging in real-time to minimise solar exports and peak period consumption, saving you the most money possible.

Key ElektroBank features:

  • 14 kWh (usable) lithium-ion polymer technology enables daily cycling (40,800 lifetime kWh) over 10-year warranty

  • Patented battery technology boosts its capacity during emergencies (Elon mode)

  • 7 kW of high efficiency (99%) Maximum Power Point Tracking (MPPTs)

  • 5 kW of high efficiency (~97.5%) hybrid inverter capacity minimses energy losses

  • Electric water heating optimisation(optional extra)

  • 5 kW power outage backup

  • Higher 105V round-trip efficiency than 48V battery systems

  • High reliability, maintenance free, all-in-one design

  • Virtual Power Plant (VPP) compatible

  • Intelligent solar PV, battery and electric water heating management software

  • 100% Australian designed and manufactured2

Why are we less expensive than the competition?

The ElektroBank is less expensive than the competition per warranted kWh because we offer an all-in-one device that saves on installation and integration costs, we have lower overheads and profit margins than the competition. This all adds up.

The ElektroBank offers the second lowest cost per warranted kWh of the seven most popular storage retrofit solutions we assessed (current as of 30 Apr 2019), including the cost of the inverter (where required) and the cost of installation. These prices are net of any available rebates.

For people installing storage at the same time as their solar PV systems, the savings are even higher, as the ElektroBank is an all-in-one unit, meaning its inverter and installation costs are effectively free in this scenario.

Please contact us  if you would like more information regarding the above analyses.

How do we save you more than the competition?

The ElektroBank automatically adjusts to changes in household and solar PV output in real time to minimise the amount of energy exported at lower value. This maximises the amount of solar PV energy used within the house, which is always more valuable than when exported.

The ElektroBank also automatically adjusts to changes in household and solar PV output in real time to minimise the amount of energy used during the peak period, minimising relatively high, peak period charges for households on a Time-of-Use rate.

The figure below, from one of our customers, shows the ElektroBank completely offsetting peak period consumption. This occurs every day that there is sufficient solar PV output. On cloudy days, the ElektroBank automatically charges from the grid to minimise peak period consumption.

We estimate that the ElektroBank delivers 85-95% of the system’s theoretical value, i.e. if we knew exactly what tomorrow’s solar PV generation and load would be. 90-95% of our performance is due to our ability to read the front of house meter to detect if exports or imports are occurring. This means that 5-10% of our performance is due to our ability to forecast solar PV generation and load patterns.

How much will this system save me on my electricity bill?

How much you save with this system depends upon your retail electricity contract, how much electricity you use and if you have a smart meter, when you use it. You can see how much a typical electricity consumer would save with our system here.

Analysis of our system’s impact on actual residential load data in NSW shows our 7 kW solar PV and 14 kWh storage deal resulting in a net refund for consumers using 5 MWh of energy per annum, and a 47% bill reduction for electricity consumers using 15 MWh.

What warranty are you offering?

Empower Energy’s ElektroBank hybrid inverter and storage warranty is among the best in the industry, with a 10-year, 40 MWh of energy guarantee. A comparison of warranty terms from leading storage equipment providers is available here, please let us know if anything is out of date here.

What happens if I have a non-standard installation?

Our installation costs assume a basic installation cost. Examples of situations that are excluded from a standard installation include major rewiring of your switchboard, tilting of your solar PV or a tile racking system, working at heights and the need to pour a cement plinth.

We offer a free* site assessment to positively identify whether you have a standard installation or not. The assessment will provide a list of extras and a no obligation quote if your installation is found to require additional work above that which is included in our standard offer.

What happens if I cannot fit that much solar on my roof?

Empower’s installation team will strive to fit all 7 kW on to your rooftop. However, if we are unable to fit all of the solar PV on your roof, we can install a 6 kW or 5 kW system, for slightly less. The reason that the lower solar PV systems are not much less is due to the available government rebates, which favour larger installations over smaller ones, at least for our solution.

How long will this system power my house for during a blackout?

The ElektroBank can power up to 5 kW of your house’s load for up to 2.8 hours at maximum load. However, most houses only use 1-2 kW per hour, so you may be able to run for 7-14 hours without power. Also, the ElektroBank can run off of solar PV during an outage, increasing operating times.

Please note that only simple backup configurations are included in the standard offer. Significant rewiring of your switchboard will incur an additional cost.
