technology will boost the battery charge current through tracking the MPP. Assuming 100% conversion efficiency of the solar system, in that way, the following formula is established: Input power (P )= Output power (P Input voltage (V ) *input current (I ) =Battery voltage (V ) *battery current (I Normally, the V...
Figure 1-3 Mutil-MPP Curve If the program works improperly after appearing Multi-MPP, the system will not work on the real max. power point, which may waste most solar energy resources and seriously affect the normal operation of the system. The typical MPPT algorithm, designed by our company, can track the real MPP quickly and accurately, improve the utilization rate of the array and avoid the waste of resources.

A) Bulk Charging In this stage, the battery voltage has not yet reached constant voltage (Equalize or Boost Voltage), the controller operates in constant current mode, delivering its maximum current to the batteries (MPPT Charging). B) Constant Charging When the battery voltage reaches the constant voltage setpoint, the controller will start to operate in constant charging mode, this process is no longer MPPT charging, and in the meantime the charging current will drop gradually, the process is not the MPPT charging.

ATTENTION: Le contrôleur procédera à une compensation de température pour les paramètres de chargement en fonction de la température de l'appareil. AVERTISSEMENT : Dégât sur l'équipement! Ne placez jamais le capteur de température dans une batterie. Le RTS300R10K5.08A aussi bien que la batterie seront endommagés. The included remote temperature sensor (RTS300R10K5.08A )is recommended for effective temperature compensated charging.

Figure 2-2 Connection Diagram Battery Connection Connecting a fuse in series through battery positive (+) in the circuit and the battery circuit fuse must be 1.25 to 2 times to the rated current. Keep OFF before connection. Connect battery positive (+) and negative (-) to battery terminals on the controller in the figure 1-1.
NOTE: Load short circuit protection and the reversed polarity connection will trigger automatically. WARNING: Controller will be damaged when the PV array reverse polarity and the actual operation power of the PV array is 1.5 times greater than the rated charge power! 2.5 Power Up CAUTION: The controller is only powered by battery, so it will not work when connected only to solar input.

5 Protections, Troubleshooting & Maintenance 5.1 Protections PV Over Current The controller will limit charge power in rated charge power. An over-sized PV array will not operate at maximum power point PV Short Circuit If the PV array short circuit, the controller will stop charging, clear it to resume normal operation.
Load Over Load Load will be switched off when 1.05 times rated current overload happens. Controller will automatically attempt to reconnect load for 5 times. If overload protection still exist after controller‘s 5 times attempts, user have to reduce load appliance, then press the button or repower the controller or wait for one night-day cycle (night time>3 hours) or press button.
