DC Current Sensors Play a Vital Role in Managing Stored Solar Power

Of course, utility companies still need an accurate DC current sensor to ensure that the batteries won’t become overloaded. If not, the power storage units may get damaged or become unstable like the power grid. Fortunately, companies like Aim Dynamics offer DC or AC current sensors designed specifically to prevent this scenario. These tools, along with the batteries, serve as a viable stopgap until Hawaii can upgrade its power grid to better accommodate solar energy produced by households.
