feflo: Solar Cable
High quality wire is a key factor for your system. choosing the lowest cost wire usually result in systems that are inefficient. For solar current, high grade solar wire is the best option. We sell pure copper solar wire, encased in a rubber sheathing.The rubber sheathing on solar wire protects against electrical shock in damp conditions and prevents damage from outdoor elements and the sun.

Batteries

How much power does a battery hold? True deep cycle batteries contain Watts, AMPS and Volts. Viewing the label on a battery, we can see how
many volts and amps a battery contains. By multiplying the VOLTS times
the AMPS we can estimate how many WATTS of power that battery holds.



VOLTS x AMPS = WATTS PER BATTERY

6 Volt Battery x 250 AMPS = 1,500 Watts

12 Volt Battery x 100 AMPS = 1,200 Watts



Using Solar to Charge a Battery

The big question – How long will it take to charge a battery? If a battery
holds about 1,200 watts of power. It would probably take a 100 watt
solar panel about twelve hours to charge that battery from empty to full.
In comparison it would probably take a 50 watt solar panel about twenty
four hours to charge that same battery from empty to full.

The above was culled from solarpenny.com

ceejay80s: Ì need 30AH or 50AH deep cycle battery

cccimisioluwa: what is the cost of 200ah
and what make do you have and you guarantee period. thanks

arbitrage: Thanks for feedback but here above is the question I asked before

alldruns1: Alright, d explanation is now clear. Hoping 2 see d pic shortly.

alldruns1: Are u referring 2 d point where u plug in appliances on d inverter e.g. TV, fan, etc? If yes, does it mean it serves dual purposes? As in, u plug in your tv there & u also charge wt Nepa light frm there? Like I'm nt getting something clear.... Pls clarify.

Pls make it asap.

alldruns1: 1. Is d auto change-over a separate item frm d power inverter itself or inbuilt.

2. Frm d pic I see, one end of d inverter hs two terminal heads where u connect your +ve & -ve cable heads while d other end is d outlet where u plug your device. How then do I charge d power inverter with Nepa light? Or is it only charged by deep cycle battery? Or is its charger a separate item too
Thnks in adv.

feflo: PWM Controllers:

A FET switch is used, under control of some algorithm, to
rapidly connect a power source, to a battery. The switch "makes" and "breaks"
many times a second, to control the charge. (Pulse Width Modulation)
When the battery is quite low, the FET switch is ON, and the
panels are connected directly to the battery, and since PC panels are a
"current source" their voltage drops (or is pulled low to the battery
voltage) and some power is lost, depending on the difference of the Vpmax
of the solar, and the present voltage of the batteries.
PV voltage - Battery voltage = Difference x Amps = Lost wattage

Note if the array was a 200W array, amps would be 11.11Aa
18V @ 11.11A = 200watts
Assuming the voltage of the battery is 12.2V, then the power loss will be

18V PV - 12.2V battery = 5.8V @ 11.11amps = 64.438W lost
So a 200W panel array will only give 135W of power to the battery

arbitrage: You didn't answer my question in the past, earlier up in your thread here but I hope you will do this time. Is this power inverter better or advisable than going for pure sine wave inverter?
