Let's keep eye on fake and simple solar charge controller

Article source:www.olyssolar.com Popularity:841 Editor in charge:solar charge control Release date:2019-03-19

Every year March.15th is a day of crack down on fake products in China, today SHENZHEN OLYS COMPANY LIMITED would like to share you some information about fake and simple solar charge controller. Based on our experience manufacturing solar charge controllers over more ten years,  we have observed that simple solar charge controller tend to make the following mistakes:

They undercharge batteries with high internal resistance (due to sulphation or bad connections);They can boost charge a battery too often if an occasional heavy load is applied;Under some conditions the charge current can oscillate rapidly on and off causing annoying flickering if any lighting or other voltage sensitive equipment is connected, This fast switching can cause annoying radio interference.

They waste energy in the afternoon when the batteries are full;Voltage transients due to inverters or large inductive loads such as motors can cause incorrect changes in regulator state.Can OLYS controller do better than this?

Yes, Imagine a human battery technician was controlling the charging. An experienced operator would not make a decision about battery condition based on only one piece of information (ie. the current battery voltage). The operator would ask such questions as how much was the battery used last night, how quickly did the battery voltage rise, how much charging has taken place today, are the users on holiday, how many days since I last did a boost charge and so on. Having put all the information together, an intelligent decision could then be made. Can we distill the intelligence of a good operator and build it into a regulator? This is what we have tried to do with our MPPT regulator range.
