5. DB Grid Charged Inverter PR301 Renewable energy series Light and power from batteries By Microsolve C C User Manual Thank you for purchasing this state of the art product This product has been designed to provide years of trouble free service Introduction This unit serves as an alternative electrical supply DB to any existing grid supplied home to provide limited power via an inverter running off batteries The main features is the simplicity of operation to the user Depending on the control switch position the system can supply power upon a power failure or load shedding situation automatically or can be under the control of the user via a panel mounted control switch The user simply ensures that any equipment powered by the wall mounted DB inverter is what is required and any nonessential appliance is switched off to preserve energy in the battery for the limited powered appliances The only understanding the user must have is that there is a limited amount of energy stored in the battery and it will power whatever is connected to the battery for a fixed period of time The amount of time that the inverter runs will be directly linked to battery size and load consumption that is the number of appliances powered by the inverter The higher the load consumption the less time the battery will be able to maintain power to the load via the inverter The unit has its own DIN rail mounted circuit breakers not only to offer overloa
