Upgraded Small Panel Powered Solar Tracking Controller
Working principle:
HWL-SP-V1 is a small panel powered solar tracking controller,
developed by Good Future Solar. Built-in lithium battery, equipped
with self-developed intelligent charge and discharge management
module, intelligent management system of battery charge and
discharge under different ambient temperatures, charge with
constant current and voltage, intelligent protection of the
battery, prevent the battery from overcharge or discharge, improve
the service life.

Advantage:
1. Max terrain tolerance adaptability in N-S direction up to 15%.
2. Excellent compatibility with all the main solar modules
available in the market, framed, frameless and bi-facial.
3. Independent 2P configuration design, which reduces the quantity
of posts and the construction cost significantly.
4. Free obstacles among rows in N-S direction, easy for maintaining
and cleaning.
5. Design configured with one single set of controller, which
ensures point-to-point real-time monitoring, easy to detect fault
points in time and reduce output loss.
6. Can move to scheduled position when there is wind ;
7. East-West orientation limiting ;
8. Wrong battery pole connection protection, with over-current
protection fuse;
Functions:
1. Smart control algorithm. Adopt time control + angle sensor to
form closed-loop control, no Angle accumulation error,
high-precision and reliable tracking;
2. Comprehensive protection mechanism. Wind protection, snow
protection, limit protection, over-current protection, over/under-
voltage protection, etc;
3. Fault self-diagnosis mechanism. System automatic detection,
automatic judgment, automatic alarm, automatic recovery after
troubleshooting, etc;
4. Modular design, easier for on-site troubleshooting and
maintenance;
5. Working temperature: -40℃ ~ 70℃;
6. Protection grade IP68, suitable for all kinds of outdoor
environments;
Business Scope:
1. Provide PV project related technical solutions to customers:
from early planning to designing, from installation guidance to
daily O&M, provide customers with complete technical support,
technical consultation and training;
2. Selection, designing, manufacturing and installation guidance of
the single-axis tracking system for PV power plant;
3. Complete supply chain of high-quality PV product components.
4. Research and development of emerging industries such as charging
and energy storage.
