The Axiom DC Isolator 25A IP66 is designed for superior performance in solar applications, providing reliable and efficient isolation for photovoltaic systems. With a current rating of 25A and a voltage rating of 1500V, this isolator is ideal for a variety of solar installations, including inverter applications and DC solar pumps.
zappi & eddi come with one wired CT clamp as standard.
The 22kW 3-phase zappi come with 3 CTs as standard.
If you would like to see real-time generation from your solar/wind system displayed on the LCD display of your product, you’ll need an additional CT (additional option).
In some cases, extra CT clamps are required i.e for 3 phase installs.
The CT comes with a 5m cable. If a longer cable is required it can be extended using CAT5 Ethernet cable or why not consider using the myenergi harvi to connect the CT over wireless?
The Axiom DC Isolator 32A IP66 is designed for superior performance in solar applications, providing reliable and efficient isolation for photovoltaic systems. With a current rating of 32A and a voltage rating of 1500V, this isolator is ideal for a variety of solar installations, including inverter applications and DC solar pumps.
Designed for solar rooftop fire protection, the BFS-S Series fire safety switch offers a string-level load break disconnect solution.
