THE SOLAR PANELS: MONO OR POLY?
PANELS THAT OFFER THE BEST PERFORMANCE PER SQUARE FOOT: The WattMobile solar panels are made of monocrystalline cells with the highest yield on the market. That way, we maximize every inch we use on your RV roof.
ABILITY TO REDUCE LOSSES DUE TO SHADE: The WattMobile solar panels are also equipped with a diode device to reduce losses due to shadings. This type of solar panel is the most effective for mobile installations such as RVs, boats and outdoors activities.
THE CHARGE CONTROLER: MPPT OR PWM?
MPPT CONTROLLER = FASTER CHARGE
- Up to a 40% FASTER CHARGE WITH AN MPPT CONTROLLER
- GET THE FULL OUTPUT PRODUCED BY YOUR SOLAR PANEL
- With a PWM controller you can lose up to 40% of the energy produced by your panel
Compare apples with apples
Most solar companies offer a PWM controller in their kits
DO NOT GET FOOLED, ASK FOR AN MPPT CONTROLLER
ALL OUR DELUXE KITS COME WITH AN MPPT CONTROLLER AND A REMOTE DISPLAY
- Bluetooth connection to your smartphone
- Compatible with lithium batteries
To understand the Why and the How:
Hypothesis:
- A 200-watt panel produces 150-watts of energy.
- On the market, most of the 200-watt panels uses a voltage of 20 volts.
- Battery voltage status: 12-volts
So the charge offered by the panel is:
- 150-watts/20-volts = 7.5 amps. A current of 7.5 amps is coming out of the panel.
The PWM controller will charge at 7.5 amps.
- But 7.5 amps X 12-volts = 90-watts of energy is transferred to the battery.
- You lose 60-watts out of the 150-watts produced by the panel.
The MPPT controller will convert the 20-volts into 12-volts.
- 150-watts/12-volts = 12.5 amps minus a conversion loss of 10% = 11.25 amps.
A charge of 11.25 amps is transferred to the battery, which is 135-watts out of the 150-watts produced by the panel.
THE INVERTER: PURE SINE OR MODIFIED WAVE? WHAT POWER LEVEL?
Pure Sine or modified wave: A pure sine wave inveter converts the 12V-DC from the battery bank into a identical current to the grid. The waves are identicals and the regular rhythm. A modified wave inverter produces current good to power the devices, but the wave is not like the current on the grid. You should avoid using a modified wave inverter with medical and good quality electronic devices to avoid damaging them.
Power: To determine the power you require you must add the consumption of all the devices that you plan to use at the same time. We also recommend not using the inverter to is full capacity for a long period of time. Just like a car that you will run at high RPM, you will damage it. For example, if you plan to use your microwave ,you require a minimum of 1500-watt inverter, but a 2000-watt inverter will allow you to use other small devices at the same time.
