Specifications
Product Description
The DC PV Protection Box GAVE STM21025P15S/4 4 MPPT 2 Strings 15A 1000V is a professional DC panel that centralizes, in a single IP65 IK7 and Class II enclosure, all critical functions to protect and isolate photovoltaic generators with four MPPT trackers and two strings per MPPT (8E/8S). It incorporates 15 A gPV fuses per pole and per string, independent DC disconnectors of 25 A–1000 V for each MPPT, and Type II PV surge protection devices also per MPPT. This architecture simplifies wiring, speeds up commissioning, and ensures fast and safe maintenance in advanced residential, light commercial, and C&I installations.
Main Features
- Native topology: 4 MPPT × 2 strings per MPPT (8 inputs / 8 outputs with differentiated polarities).
- String protection: 15 A 10×38 mm gPV fuses installed on the + and − poles of each string (16 fuses in total).
- Dedicated disconnection per tracker: 4 DC disconnectors of 25 A at 1000 V allowing safe operation and maintenance per MPPT.
- Surge protection: Type II PV SPD per MPPT (In 20 kA · Imax 40 kA · Up ≈ 3.6 kV · Uc ≈ 1060 VDC).
- Polycarbonate enclosure, double insulation Class II, IP65 and IK7, suitable for outdoor use depending on installation.
- Internal DIN rail distribution with accessible terminals, clear labeling, and space for PV cable 4–6–10 mm².
Advantages or Benefits
- Faster and cleaner installation: grouping by MPPT, identification of strings and polarities, and reduced risk of connection errors.
- Comprehensive DC side safety: load disconnection, selectivity by gPV fuse, and transient discharge via Type II SPD.
- Agile maintenance: MPPT isolation in seconds, easy replacement of gPV cartridges, and visual verification of SPD status.
- Technical compliance: components and construction aligned with best practices and IEC/EN PV protection standards.
- Outdoor robustness: IP65 and IK7 sealing that protects the equipment against dust, water, and impacts.
Purpose or Applications
Designed for string inverters with 4 MPPT and input up to 1000 VDC working with two strings per tracker. It is ideal for high-power residential rooftops, small ground-mounted plants, and light C&I where MPPT disconnection, string fusing, and dedicated surge protection are required, keeping the DC panel organized and ready for audits, preventive maintenance, and future expansions.

Compatibilities
Compatible with four-tracker inverters (Huawei, Fronius, SMA, GoodWe, Solis, Deye, etc.) that support 2 strings/MPPT and input up to 1000 VDC, provided that the Isc of each string is ≤ 15 A and the Voc_total at the minimum project temperature does not exceed 1000 VDC. Requires equipotential bonding of the structure, low-impedance grounding, and coordination with the inverter/upstream SPD.
