D. What to do with a large amount of cold-rolled plates and rust? What to do at sea?

MPPT&PWM

The full name of MPPT is “Maximum Power Point Tracking”, which is an advanced charging method. The MPPT controller can detect the luminous power of the solar panel in real time, and track the highest voltage and current value, the tracking efficiency is greater than 99%, so that the system can charge the battery with the highest efficiency. Compared with the traditional PWM controller, the MPPT controller can exert the maximum power of the battery panel, so it can provide a larger charging current. Generally speaking, the MPPT can increase the energy utilization rate by 15% to 20% than the PWM controller. And extend battery life, 10% more than the first generation.

J.System status record, the system status can be recorded for up to 7 days, and the system can be fully monitored.
K.Real constant current control instead of current limiting, to ensure smooth and stable output current, thereby reducing LED light decay and prolonging LED service life.
L.Metal shell, IP67 waterproof grade, can be used in various harsh environments.
M.Overheating protection function, over a certain temperature will reduce the load or shut down the load.
N.Battery reverse connection protection, LED short circuit protection, open circuit protection, etc., so that the system is fully protected.
