Our engineers are ready to help you select the best controller for your specific application.
Consult a Technical ExpertSUNOPEN MPPT controllers cover six core off-grid scenarios: security and surveillance cameras, telecom base stations and IoT gateways, RV / caravan / marine systems, solar street lighting and traffic safety equipment, oil & gas and mining monitoring, and rural electrification for communities without grid access.
Yes. Our MPPT controllers deliver continuous power for CCTV and remote monitoring, absorb the surge current of PTZ motors, and keep charging stable from -35°C to +60°C ambient temperature.
For remote base stations, microwave repeaters and IoT gateways, pick a Buck MPPT matched to your battery bank (12V / 24V / 48V) with a current rating above the panel short-circuit current. Add a Bluetooth, WiFi or 4G module for remote diagnostics and fewer site visits.
Yes. The 800W Boost MPPT (H20TB) charges 48V-72V battery banks on yachts and motorhomes, while the 450W Boost MPPT suits e-scooters and light EVs. Both are compact, fanless and sealed against salt spray.
Industrial-grade hardware with conformal-coated PCBs, a wide operating temperature range and fail-safe power delivery keeps sensors, flow meters and pipeline monitoring equipment running in hazardous, unattended locations.
We supply cost-effective, durable MPPT controllers for residential off-grid systems in developing regions, with OEM / ODM options and volume pricing for government and NGO electrification programmes.
