Power Output

Continuous power is a measurement, expressed in kW, of a battery's potential to release a sustained energy for a given period. Peak power is a measurement, expressed in kW, of a potential maximum power output in short bursts.

The Franklin aPower X provides 10 kW of peak power and 5kW of continuous power, well within the range of solar industry standards.

Round-Trip Efficiency

The Franklin aPower X has a roundtrip efficiency rating of 89%.

In order for a battery to function, a small amount of electric power is required for its operation. The total amount of charge that comes out of a battery subtracted from the amount of charge that went into the battery is expressed as a percentage ('%'). This is called Round-trip Efficiency.

The Franklin Power X has a rating of 89% round-trip efficiency, 9% above average.

The Franklin aPower X Dimensions are 31.5” x 21.7” x 6.3”
