The 400 watt solar panel is a high-performance module. Renogy manufactures these rigid and strong solar modules.
They call it the Renogy 400W Monocrystalline Starter Kit. It is a High-Efficiency Monocrystalline Solar Panel.
The system uses 4 x 100 Watt solar panels to deliver a peak output of up to 400 Watt on a sunny day.
The module comes with an efficiency of 21%.
The four 100w panels take up about a 3ft x 8ft space.
You can connect the four Renogy 100-Watt Monocrystalline solar panels in parallel.
Do it by making use of three pairs of branch connectors. The branch connectors come with the kit.
The modules come with TPT (Tedlar Polyester Tedlar) back sheets. This is to ensure smooth performance over a long period
They use heavy-duty anodized aluminum frames for solar panels. That provides for high-quality panel rigidity.
One can use these solar panels for many years. You will experience no faults, defects or operating failures.
It comes with a superb warranty for up to 25 years.
On a sunny day with 6 hours of sunlight in mid-summer, you can bargain for the generation of about 2 Kilowatt.
That is 6 x 400 watt = 2.4 Kilowatt.
Now you allow for a loss of 15% and you get 2400 X 85/100 = 2.04 KiloWatt
Throw away 0.04 and you get a fair 2 Kilowatt.
Four Renogy 100W 12V Monocrystalline Solar Panels
A 30A PWM Wanderer Charge Controller
A 20ft 10AWG MC4 Adaptor Kit
An 8ft 10AWG Tray Cable

Four sets of Z-brackets. (Four Z-brackets per set.)
To make the 400 watt solar panel fully operational we need a charge controller, battery and an inverter.
It comes with a 30 Amp charge controller.
Size the battery by dividing the total watt by volts.
This is 400 watt x 6 hours sunlight ( Depending on your area.) X .85 for losses/ 12 volt x 2 for DOD.
This is 400 x 6 x .85 / 12 x 2 = 340 Amp Hours .
A 2 x 200 Ah batteries will be a good choice.
Size the inverter by deciding the max watts to be utilized at once.
The max output of the panel is 400 watt.
Rule of thumb is to use an inverter 1.25 to 1.5 times more than max watts.
In this case we can work with a 400 x 1.5 = 600 watt. A 600 watt inverter will be a good choice.
Maximum Power: 100Watt.

Weight: 16.5 pounds.
It comes with a 25-year power output warranty:
5 Year/95% efficiency rate.
10 Year/90% efficiency rate.
25 Year/80% efficiency rate.
The 400 watt solar panel kit also comes with a 5-year material and workmanship warranty.
Accessories come with a 1-year material warranty.
Use the 400 watt solar panel starter kit for various
off-grid applications such as:
Electric livestock fences;
The starter kit can provides years of quiet power production and grid independence.
Do not worry about rainy and misty weather. The 400W solar panel will perform well under these harsh conditions.
The 400 watt solar panel comes with a corrosion-resistant aluminum frame. This is for extended outdoor use.
These are heavy-duty frames
allowing the panels to last for decades.
The Renogy Wanderer 30A
Negative-Ground Charge Controller works with Pulse Width Modulation.
The condition of the battery
determines how the current tapers from the solar panels.
The PWM algorithm reduces the charging of the battery.
This is when it reaches the regulation set point.
This is to avoid heating and gassing of the battery.
Charging will continue to ensure the provision of the largest amount of energy in a short time.
Nominal Voltage: 12 VDC.
Rated Charge Current: 30A.
Max. PV Input Voltage: 25 VDC.
Max. PV Input Power: 400W (12V).
Battery Type Sealed, gel and flooded.
Charge Stage 3.
Grounding Type Negative.
Nominal system voltage 12V DC.
Dimensions 6.5 x 4.3 x 1.8 In.
Remember when connecting it
is important to first connect the battery. Then connect the load and last the
solar module itself.
This is to ensure safe
operation and safeguard equipment against overload.
One should never connect the
solar panel to the controller without a battery.
It is good practice to
install the charge controller indoors to keep it well ventilated, cool and dry.
Keep the controller away from damp.
It is better to install the
charge controller indoors in a well-ventilated, cool, and dry place.
Do not allow water to enter
The kit comes with a 20ft 10AWG MC4 Adaptor Kit. This is to connect the solar panels to the charge controller.
Also, an 8ft 10AWG Tray Cable to connect the charge controller to your battery.
Setting it up is quick and easy.
The 400-watt solar module
kit includes 4 sets of Z-brackets.
One set per panel and four Z
shape solar panel brackets per panel.
The brackets make mounting
of the panels easy, safe and secure.
Some people report that the screws in the charge controller are not strong enough. It is the ones that hold the wires from the solar panels.
It would be easier to connect the solar panels via four-way connectors.
The 400 watt solar panel kit
is high quality and the panels are efficient, even on cloudy days.
The charge controller comes
with many useful displays to track everything important.
The complete system is
unbelievable easy to install.
The 400 watt solar panel is a high-performance module.
This is a well-manufactured solar module from Renogy.
