Project Overview
Contractors move power to wherever the work is. SL-86 wheeled solar generators and trolley ESS units deliver pure sine temporary power for tools, lighting towers and site offices.
Customer Challenge
Diesel gensets create noise, fuel logistics and emissions issues on urban sites. Teams also need units that fit in vans and roll across rough ground.
Longlight Solution
Deploy SL-86 mobile solar generators for higher loads and SL-100-S3 trolley ESS for mid-power crews. Portable panels keep packs topped up during daytime shifts.
System Architecture
- Portable PV foldables charge onboard storage
- Wheeled inverter-battery unit at point of use
- AC / DC outputs for tools, lights and radios
- Optional multi-unit staging for larger crews
Key Products Deployed
Technical Highlights
- No on-site fuel handling for short jobs
- Quiet enough for night work near residences
- Rollable form factors for temporary deployment
