A dual power supply provides two output voltages: one positive and one negative with respect to a common ground. For example, a ±12V supply gives +12V, -12V, and 0V (ground). Many analog and mixed-signal circuits such as op-amps, analog sensors, and instrumentation systems.
All-in BESS projects now cost just $125/kWh as of October 2025 2. With a $65/MWh LCOS, shifting half of daily solar generation overnight adds just $33/MWh to the cost of solar.
