High‑performance 100 A MPPT solar charge controller with built‑in Bluetooth for real‑time monitoring and advanced battery management.

• Ultrafast MPPT technology – maximises energy harvest (up to ~30% vs PWM, ~10% vs slower MPPT) and maintains performance in low‑light conditions.
• Inbuilt safety protection – PV short circuit, reverse polarity, overvoltage, overcurrent, reverse current, battery overvoltage, reverse polarity and overheating monitored by internal temperature sensor; self‑diagnostic with high‑intensity LED fault indication.
• Inbuilt Bluetooth – connect with VictronConnect for live data transmission and real‑time information including solar panel voltage/current/power and battery status; data logs store system activity for the past 30 days.
• User‑defined battery charging algorithm – option to disable preset values in favour of personalised charging parameters, selectable charging stages and advanced battery settings.
• Programmable relay and alarm – configurable relay contacts for signalling or load control; AC rating: 240 VAC / 4 A, DC rating: 4 A up to 35 VDC, 1 A up to 60 VDC; audible alarm options.
• Connectivity and display – RS232 / TTL for VE.Direct accessories, RJ45 for VE.Can using a simple RJ45 cable; connection area for optional LCD display.
• Performance limits – max solar panel voltage: 250 V; max solar panel power: 1450 W (12 V) / 2900 W (24 V) / 4350 W (36 V) / 5800 W (48 V); max charge current 100 A.
• Specifications & environment – high MPPT efficiency (>95%), self‑consumption <35 mA (48 V); working temperature ‑30°C to +60°C (‑22°F to +140°F); enclosure IP43 (electronic components); Pollution Degree PD3; IEC/EN certified.
• Mechanical details & documentation – dimensions 216 x 295 x 103 mm (8.50 x 11.61 x 4.Ø 6 in); mounting dimensions 273 x 144 mm (10.75 x 5.67 in); weight 4.5 kg (9.9 lb); 4 x mounting holes (8 mm diameter). User manual for VSSM250‑100 available to download.
