 During the preparation of large-scale projects (WB Indonesia 200,000 SHSs, WB Sri Lanka 30,000 SHSs) and the worldwide PV GAP program an international standard for charge regulators is required, with specifications that can be objectively checked and tested by any qualified test laboratory. The CENELEC CLC/BTTF 86-2 committee has actually drafted a standard for charge regulators in Solar Home Systems, which was also accepted by the IEC TC 82 and is currently circulating among the committee members for discussion and correction. A copy of the current draft version (as of 07/98) was kindly made available by TÜV-Rheinland, a member of the standards committee. The final version of this standard will probably be released by the end of 2000 and will not differ much from this draft.<br/>

The charge regulators shall have been manufactured from specified materials and components in accordance with the relevant drawings and process sheets and have been subjected to the manufacturer’s normal inspection, quality control and production acceptance procedures. If the charge regulators to be tested are prototypes of a new design and not from production, this fact shall be noted in the test report.<br/>

-The main requirement for a charge regulator should be that the unit itself will not become the weakest or most vulnerable component in the whole system (which unfortunately was the case in several projects in the past). From all of the experience over the last 15 years, some quite reliable equipment has been developed by various companies. The optimisation of charging characteristics and safety precautions is an ongoing development process, as highly integrated electronic components nowadays allow very complex regulation features in a minimum of space and with low productioncost requirements.<br/>

 Basically, there are two kinds of charge regulators; the main difference lies in the position of the switching device. <br/>
-The "Series" type interrupts the connection between the solar generator and the battery, while the "Shunt" type short-circuits the solar generator. In addition, there are two main types of control strategies. In a "Twostep" control arrangement, the charging current is completely interrupted when the endof- charge voltage is reached. With a "Pulse-Width Modulation" control, on the other hand, the charging current is gradually reduced to the end-of-charge voltage level, thus keeping the voltage constant. In SHSs, both types of regulators and both control strategies serve the purpose equally well. In fact, recent systematic and independent testing experience does not suggest that there is any real advantage associated with either type of regulator or control strategy in terms of improvements to battery lifetime.<br/>
