WindyNation 100w Solar Panel Off-Grid RV Boat Kit Review | 2020 Review

The WindyNation 100w Solar Panel Off-Grid RV Boat Kit – Works on the principle of capturing energy from the sun.

Gathered energy is passed through to the charge controller which in turn feeds it to the battery for storage.

  • The primary role of the Off-Grid RVs is thus, nothing but battery charging.
  • WindyNation 100w complete kit has everything needed to produce free and clean power from the sun.
  • Whether this is for a boat, cabin or power backup, this kit has everything needed for providing the power.
  • On the top of it, it is also simple to install and comes at an affordable price.

The home solar panel kits include a piece of 100-watt solar panel, User adjustable LCD 30-Amp Solar Charge Controller with Battery Temperature Sensor, 40 feet of UL Listed 12 AWG Solar Cable, all necessary MC4 Connectors for wiring, and all the necessary mounting hardware (4 Solar Panel Mounting Brackets and Fastener Sets).

A 12-volt battery and a DC-to-AC convertor is all that is required to turn the energy of the sun into power. A digital display also comes along with this kit and this display provides system information about the battery voltage, temperature, etc. The charge controller has MODE, UP and DOWN buttons to adjust system settings like voltage of solar disconnect, voltage of load disconnect, etc.

The Charge controller is WindyNation’s P30L PWM 30 Amp solar charge controller. This controller has the ability to prevent the battery from overcharge. This ability saves the battery from damage due to overcharge by the solar panel.

  • The controller has been designed to provide multifunctional charging and power management for solar charging of 12 and 24-volt battery systems. The controller has a detect function to identify the battery voltage upon connection.
  • There is also an inbuilt protection to provide protection to the battery during overload, short circuit, reverse polarity, lightning/surge, PV Panel Reverse current, overcharging and discharging.

This helps the system in remaining undamaged in the event of short circuit or overload. The parameters of these controller can be controlled by the LCD screen display. The controller is enclosed by using durable plastic.

LCD Display:

The charge controller has an LCD display. With the LCD display, it is easy to adjust the different settings and the power output of the instrument. The LCD Display also displays various other factors like the DC load draw, temperature, voltage, amperage, and a lot more, with the charge controller.

Solar Panel Mounting Bracket and Fastener Set:

The Mounting Bracket and fastener set is made up of anodized Aluminum and stainless steel. These are corrosion resistant materials and has a longer life. There are 4 anodized aluminum brackets Z-brackets and 4 sets of stainless steel fasteners. These brackets and fasteners helps in quickly and easily mounting the solar panel to a boat, roof or RV.
