Note:

Maxium Votage is 50v, 30A.Parallel connection, Series connection are both okay.
Don't put the controller in the liquid with corrosivity, because do it will damage the controller and produce some harmful gas
The voltage of the battery panel may exceed the safer voltage of people when connect the 24V system, you had better use the insulation tools and keep your hands dry when need to operate it
Don't let the storage battery become short circuit when the storage battery with full of power, we highly suggest that connect the fuse on the storage battery
The storage may produce some flammable gas, please keep away from the fire
Let the little children away from the storage battery and the controller

Package includes:

1 x Digital PWM 30A Solar Charge Controller
1 x User manual

• Five load working modes: pure lighting control, lighting control & timing control, hand operation and debug mode
• Various protections include over-charge, over-discharge and over-load, as well as unique electron short circuit protection and connection-reverse protection. All the protections are harmless to any parts and fuse; fuse only as the end protection of a controller itself to protect the amount of internal short circuit damage. None wore jumpers design improves the reliability and durability of the products
• Scientific management of battery: as it is overcharged, the battery will get booster tension charge. As a result compulsory maintenance is available for the battery. In normal working state, the direct charge and floating charge are both available, so that the battery life-span is increased. Besides, the adoption of high precision temperature compensation makes the charging more accurate
• Our controllers are specially designed for solar power DC supply system, solar power DC street lamp system and mini solar power station system.
• Shipping from TX of United States,2-5 business days.
