Jaycar 100A 6.5-100V DC Power Meter with External Shunt

You've got a dedicated solar-plus-battery setup pushing serious amps, and a 20A meter just isn't cutting it. This Jaycar 100A DC power meter handles up to 10kW of system capacity, and the external heavy-duty current shunt keeps the wiring clean and reliable at those higher loads. You get real-time power, voltage, and current on a bright blue backlit display, plus total energy throughput with a one-button reset. Whether you're tracking generation on a sunny Tuesday or drawing from the bank during a blackout, it's all there at a glance. Powered from the circuit itself — no extra supply to wire up
