Solar Panel Solar Set 310W + Regulator 20A

Description
The proposed set allows the use of solar energy to charge a 12 / 24V battery.
The stored energy can be used to power 12 / 24V appliances or lighting (such as from a cigarette lighter in a car). It is also possible to use a 12 / 24V to 230V AC converter to power typical electrical devices.

This kit solves the problem of access to electricity in:
a motorhome or caravan
On a boat, yacht, housebot
On the recreational plot, a summer house.

In the set you get:
1. Photovoltaic panel with a maximum power of 310W \ (typical in an aluminum frame, small SIZE, polycrystalline)
2. Charge controller with LCD display with a maximum charging current and load of 20A
3. Cables with crocodile clips for connection to the battery, 1 m long
4. Rubber, solid cable with MC4 plugs for connecting a 2m long PV panel / optional 4m or 6m

Voltage regulator 20A 12 / 24V with wilight function and 2x USB

Controller functions:
The controller has a programmable twilight sensor function.
It is possible to turn on the connected receiver after sunset for a specific number of hours.
In addition, the regulator may be expanded with additional panels in the future, thanks to which we can obtain more electricity.
The controller charges the batteries with the PWM method. It modulates the voltage range from 0 to 100%, which allows for quick and stable battery charging regardless of the weather and the condition of the solar system.
DOUBLE USB

Regulator security:
Solar battery short circuit.
Load side overload.
Reverse battery polarity.
Overheating protection.
Controller settings:

Turning on / off receivers.
Twilight switch (turning on receivers for a given time after sunset).
Programmable up to 15h.

BATTERY CHARGING TIME
The table opposite presents the time needed to charge the batteries available on the market depending on the power of the photovoltaic system.

The 310W solar battery will easily charge the 40 Ah battery in just over 2 hours from full discharge !!!

NOTE: The set does not include a battery. For this set, we recommend a gel or acid battery of at least 80Ah.

Of course, a smaller one can be used, but the amount of stored energy will be less and the service life will be shortened. Generally, the bigger the battery, the better.

The charge controller controls the charging process of the battery and protects it against overcharging or discharging.

Connection sequence:
1. Battery
2. PV panel
3. Load (bulb symbol)
CAUTION: ALWAYS make sure that you connect it with the correct polarity, i.e. plus to plus and minus to minus. Despite the security measures, incorrect connection may lead to damage to the regulator, e.g.overheating, as well as damage to the battery and the PV panel
