Make sure that the battery has enough voltage for the char controller to recognize the type of battery before first installation. Keep the battery cable as short as possible to minimize losses. The char controller is only suitable for regulation of solar modules. Never connect another load source to the char controller. Builtin short circuit protection, open circuit protection, reverse protection, over load protection. Applications and practical scenarios Offgrid solar system for a small home or cabin: ensures correct battery recognition at initial setup and provides reliable regulation of solar input with builtin protections. Mobile solar installations such as RVs, boats, or camping trailers: short cable runs reduce energy losses and support safe, efficient solar regulation in constrained spaces. Remote equipment or security systems powered by solar: dependable regulation of solar modules with comprehensive protection features to prevent damage from faults.
