What do I need to complete my off-grid solar power system ?

You need a solar panel, charge controller to regulate current, and a battery to store power. Also require adapter kit cables for panel-to-controller wiring, and tray cables connecting controller to a deep-cycle battery.

What does off-grid and on-grid mean ?

On-gnid means solar power equipment connected to the electricalgrid; off-grid means not connected to the grid, so power is stored for later use and unaffected by blackouts.

Why is my solar panel under producing ?

Solar panel performance may be hindered for a number of reasons. Most commonly environmental conditions such as indirect sunlight, temperature rise, cloudy sky, and dirt and stain build up on the top glass will cause a reduced power output.

How should I connect solar panels in my electrical circuit (series vs parallel)

Solar panels can be connected in serles or parallel to meet your circuitsize and power demand, Series adds voltage (current same as one panell, Parallel adds current (voltage same as one panel). You can use both for optimum output and system rating.

When do I need an inverter ?

You need an inverter if powering home appliances (e.g., coffee maker, TV) to convert the output voltage from a 12V DC system to a 120V AC output socket. Renogy offers various inverters to suit your system and power demand.
