ALTERNATIVE SOURCES OF ELECTRIK ENERGY

There are two inverters 12 v dc to 230 v ac.
The first (the small one is 500 w -pic 1000 w ).It can be use on boats (for 220 V) , for lighting in the countrysite , for charging mobile phones,tablets , as UPS for PC, for wood burners during a black out.It has inside a change over switch to jump automatically to the battery in a black out.
The second (the bigger is 1500 w -pic 3000 w) .
It can be use to all the cases before and also to work with electric tools in places where there is no electricity.(drills,small grinders,jig saws etc).Also to every kind of refrigerators and oil burners.
Both of them are modified sine wave inverters. In case only of brushless motors (if we use them for hours) it is better and more save for the motors to use pure sine wave inverters .(refrigerators , pumps in oil and wood burners).There is no problem for short black out if we have mod. sine wave inverter.
You can use everyone of them separate without the base.
ATTENTION IF YOU USE A UPS AS A BATTERY CHARGER BE CAREFULL WHEN YOU DISCONNECT THE BATTERY (BACK EMF CURRENT IS ABOUT 250-260 V - UPS USES COIL TO THE TRANFORMER INSIDE). TOUCH ONLY THE PLASTIC OR WEAR GLOVES).
