Month: December 2014
It has been an awesome year for us. We are thankful to our customers that have made our growth possible. Our systems can be found in Lagos, Abia and Rivers States. We have made sales in Ghana, Delta and Imo States. We can’t wait for 2015 to begin so that we dazzle you with our solution that provides electricity with no noise or pollution.
Challenges we faced
We started with an inverter that clearly did not meet our goals for our customers. They were finicky, required customer intervention and failed at the slightest provocation. Our customers were willing to adapt to the performance of the systems. We refused to accept equipment that did not deliver on the promises we made customers. The objective was to provide more than just lighting.
The replacement was on a different planet relative to the original. The 2 KW pumped water, ran the fridge and freezer, came with a powerful built in charger and was much more durable. It was also very tolerant of the poor voltage that NEPA supplied to many homes.
We also realized that batteries were the biggest key to success. The best solution was always to buy more batteries than you need. Most customers did not want to make the investment. So we had to find a battery that would survive the discharge and recharge cycle that our customers will subject them to. We picked the Trojan flooded lead acid battery to be our battery of choice. They have proven to be ideal. They require an initial boost charge before you use them. But once that is done they are awesome. They get better the more they are used. Unlike the sealed batteries, they don’t have to be fully charged daily. This is ideal for customers who have small battery banks in cloudy places, like Lagos.
Over all, it has been an awesome experience and I can’t wait to see what 2015 has to offer.. Thank you so much for your patronage, kind words and encouragement.
We wish you and your families a very Merry Christmas and a Happy New Year.
Batteries have been the most difficult challenge facing any back up or primary energy system. This challenge is hardest for people with limited funds. If money is no object you can buy your way into battery nirvana.
What is a battery? Batteries are devices that convert stored chemical energy into useful electrical energy. I guess that simplifies it enough.
What types of batteries are used for renewable energy or back up? VRLA or Valve Regulated Lead Acid (commonly called Sealed or maintenance free), Flooded lead acid and Lithium Iron Batteries. The most commonly used today are sealed or maintenance free batteries. They come in two technologies. AGM or Gel. Gel add silica to the acid to make it putty like minimizing spills. AGM or absorbed glass mat uses fiber glass between the plates to trap or contain the electrolytes. Lithium Iron is similar to what is used in your laptops and hand held devices. The other type of battery that is used is the flooded lead acid battery. They have electrolyte covering the lead plate and are not spill proof and require that you check and periodically top up the batteries with distilled water.
AWPS Energy LTD uses flooded lead acid batteries for a number of reasons. They can tolerate the abuse of being discharged and recharged better. As long as you fully charge them once a week they are fine. The AGM and GEL require that you fully charge them daily. As a battery goes through a charge and discharge cycle you are bound to lose some electrolyte. In your maintenance free batteries you are not able to replace the electrolyte you lose. If you over charge them and they vent, you have lost some gel or putty. This shortens the life of the battery.
What voltage does my battery have to be charged to for daily use? It varied from manufacturer to manufacturer. Trojan recommends a daily charge 14.8 V for your 12 V battery. Most people believe that at 12V a battery is fully charged. At 12 V your battery is 55 to 60% discharged. It is fully charged at about 12.75 V.
To get your batteries to last a long time, follow the manufacturer’s recommendations and charge them properly. If you frequently run out of batteries we advise you to increase your battery bank
