Agri Microgrid Protection: NEUTRON Scope at Themar Al Emarat Solar Farm
A DC-plus-AC protection scope for an agriculture microgrid with solar, storage and inverter-connected loads.
Electrical Protection
Research Microgrid Protection: NEUTRON Scope at a Qatar Desert Farm
A hybrid-microgrid protection approach pairing array-side DC control with Type B residual-current protection on the AC board.

Humanitarian Solar: NEUTRON Protection Scope for Zaatari Camp Solar
Solar power at the Zaatari refugee camp supports essential services such as water pumping, lighting and community facilities. NEUTRON supplied the DC protection on the array side and the residual-current protection on the AC side, with the battery and inverter integrated by the operator.

Community Solar Microgrid: NEUTRON Protection Scope at Baaloul
The Baaloul community solar microgrid brings reliable electricity to a rural Lebanese village through on-site PV and storage. NEUTRON supplied the DC protection on the array side and the residual-current protection on the AC side, with the battery and inverter integrated by the operator.

Resilient Village Power: NEUTRON Protection Scope at Menjez
The Menjez community solar system gives a rural Lebanese village resilient local power through PV and storage. NEUTRON supplied the DC protection on the array side and the residual-current protection on the AC side, with the battery and inverter integrated by the operator.
Electrical Protection
Beating Salt Mist: NEUTRON Coastal PV Protection Across the GCC
Across the Gulf Cooperation Council, many of the largest solar plants sit on or near the coast, from the UAE and Qatar to eastern Saudi Arabia and Oman. Salt mist and high humidity change the protection problem, so NEUTRON developed a coastal PV protection approach centered on corrosion-class enclosures and staged DC surge protection, applied wherever the array meets the sea.
Low-voltage protection
RCCB Sensitivity Explained: When to Choose 30mA, 100mA or 300mA
RCCB sensitivity is the rated residual operating current IΔn. The correct rating depends on whether the device is protecting people on a final circuit or providing fire protection and selectivity upstream.
Residual-current protection / Cost guide
RCCB vs RCBO Price Explained: Why RCBOs Are More Expensive but Worth It
Understand the device-level and installed-panel price difference between RCCBs and RCBOs, including protection scope, module count, selectivity and downtime.
Protection / Selection guide
Understanding Type B RCCB Pricing: A Cost Structure Guide
A Type B RCCB typically costs five to fifteen times a comparable Type AC or Type A device. The premium is not branding. Detecting smooth DC residual current requires an active fluxgate sensor, a microcontroller with signal-processing firmware, an aux
