Compact solar charge controller designed for clear monitoring and efficient battery charging Key benefits Monitor performance visually: builtin display shows the daily power generation curve and the current curve so you can spot drops in output, assess panel orientation, or detect shading and wiring issues. Improve conversion efficiency: realtime curve feedback helps you make adjustments that increase overall energy harvest from the array. Wide input compatibility: accepts PV array voltages from 18V to 80V, making it suitable for a range of panel configurations. Flexible battery support: selectable 12V or 24V output lets you use common battery banks without extra converters. Rightsized for small systems: 20A maximum output current supports small offgrid systems, RVs, boats, and remote equipment while remaining compact at 137 x 81 x 30 mm for easy installation in tight spaces. Technical highlights Input voltage: 18V to 80V Output voltage: 12V or 24V (selectable) Maximum current: 20A Size: 137 x 81 x 30 mm Function: displays daily power generation curve and current curve to help optimize conversion rates Why you need it Simplifies system tuning by providing visual data on daily yield and current behavior. Reduces guesswork when diagnosing performance issues, helping you prioritize adjustments that yield measurable improvements. Fits many smallscale solar setups thanks to broad input range and selectable output voltage. Typical applications Offgrid cabin or workshop: manage a 12V or 24V battery bank and monitor daily energy yield to optimize panel placement. Recreational vehicle or marine use: compact controller for 12V or 24V systems that provides performance curves to detect shading or connection losses. Remote equipment or signage: reliable charge control for small systems where space is limited and visual monitoring speeds troubleshooting. Installation notes Verify PV array voltage stays within the 18V to 80V input range. Select the appropriate 12V or 24V output setting for your battery bank before operation. Mount in a protected, ventilated location sized to accommodate the 137 x 81 x 30 mm unit. This controller provides straightforward monitoring and practical control for small solar systems, helping you improve energy conversion and simplify system maintenance.
