EXTENDED HEIGHT WATER MISER SAFETY VENTS FOR SOLAR ENERGY BATTERY BANKS* DESIGNED AND MANUFACTURED BY FLOW SYSTEMS* The EXTENDED HEIGHT CAPS(1.455"are ... moredesigned to allow for maximum water retention and electrolyte expansion in your SOLAR BATTERY COLLECTION SYSTEM WATER MISER Battery Caps Save your expensive batteries by saving your water! These caps will reduce water loss by 50% to 60% Keep your batteries clean and dry and extend the life of your Solar Battery Banks or other Deep Cycle Batteries. Guaranteed to Work- With 10+ years in the field and millions already installed. Flow systems will gladly accept the return of any product that does not work as claimed! Ideal for Solar. Forklift, Golf Cart, Marine, RV and Floor Scrubber Batteries- The Water Miser Safety Vent can be retro fitted to any U.S. manufactured industrial. Semi-industrial, golf cart, marine, RV or solar battery that use a 1/4 turn bayonet type vent cap. This comprises about 98% of all US batteries. Less Watering- Extended watering intervals are achieved along with reduced equalization due to the fact that very little electrolyte ever passes through the moisture return medium and hydrophobic cindered disc combination. They Stay Drier- Traditional vent caps that come pre-installed on most lead acid batteries provide a direct line of sight to the electrolyte( Sulphuric acid solution) within the battery cell allowing gasses to escape and damage battery storage compartments and other components within reach of these gases. Water Miser vent caps provide 2 barriers to escaping gases that alleviate any concern of acid damage. Batteries Last Longer- Any residual gases that escape through the moisture retention medium during the charging cycle. Carry fewer electrolyte laden droplets, assuring that electrolyte gravities are stabilized within the battery cell(s) Reduced Acid Mess- The handling of acid laden vent caps is a thing of the past- the built in"anti-splash" device assures that a minimum of electrolyte is propelled into the immediate

Panel have no connectors connectors are not included you must solder them yourself I will write small amount for customs.So avoid import tax In case of ... moreimport duties and Tax it is buyer responsibility as item will be shipped from Netherlands Technical advantages: 1. Low temperature coefficient: Normally. The electricity performance of photovoltaic module is measured by STC standard. However. The temperature of solar module. Operating in the sun. Can be much higher than atmosphere temperature. With the temperature increase, module power will decrease accordingly. Temperature coefficient for thin film silicon solar cell is 0.2%1celsius. And that of crystalline solar cell is 0.5% 1celsius. That means. When the module is worked on 80celsius condition. Compare to the efficiency reached on 25celsius test standard, thin film silicon solar module will loose around 11% from panel power. And the loss for crystalline will be around 27.5% from panel power at 80celsius In conclusion. Even the STC efficiency of thin film silicon solar cell is low. The efficiency in actual operation condition is not far away to that of crystalline solar cell. 2. Good weak light performance: The performance of thin film silicon solar cell is better than that of crystalline solar cell in the weak light condition. Solar power system with crystalline solar module will not generate power in the late afternoon. However. Solar power system with thin film silicon solar cell still generates power. Furthermore. Thin film silicon has gentle current- voltage curve. This characteristic makes it easier to pick-up the most electricity power for more quantity or any quastion please contact me more information on:

Flexcharge Solar Wind Hydro Turbine Charge Controller NC25A-24 hybrid 24 volt US Manufactured Long Service Life and Performance History We are a stocking ... moreFlexcharge dealer and these controllers come with the manufacturer's Five Year warranty. You can see us listed here on Flexcharge's dealer page: http:www.flexcharge.com/Where-to-buy.html SES Flexcharge model NC-25A/24 charge controller- 24 volt d.c. The following is copyrighted by SES Flexcharge. NC25A Ultra High Efficiency 25 Ampere Solar and Wind System Charging System Controller The NC25A-X) is series regulator designed for alternative energy charging systems ranging in size from 0.1A to 25A. It is the ideal regulator for Solar(PV) and Permanent Magnet Generators(Including outboard motors and smaller wind generators) The NC25A also includes the Charge Divert feature. Charge Divert allows you to use the excess charging source energy for other tasks. Or for placing a load on permanent magnet charging sources such as wind generators to prevent over speed conditions. The Divert connection is only activated after the charging source is making energy and the batteries are not using the energy(i.e. A wind generator will not be starting into the divert load) This controller can easily and inexpensively be expanded to handle one or more banks of 100A charging sources. 1000A max charging current in this configuration) Multiple battery banks can be charged with the use of a standard battery charging isolators. Years prior to the sale of the first NC25A. The SES Flexcharge product development team took a hard look at what a new alternative energy charge controller's performance level would need to be to give the user the best possible controller for there needs. From that effort came the following design criteria; Highest Possible. The NC25A holds a Patent for its innovative an efficient charging circuitry. Most alternative energy charge controllers operate at an efficiency of 97% Off hand. This sounds pretty good but lets go through the numbers for a typi
