Growatt SPH4000 Installation Manual

 Confirm whether the battery temperature is too high, too high temperature of battery can also
lead to SPH fail to work, at this point, to ventilation, cooling or still handle to the battery, please.
 If temperature is low, also can appear the battery low temperature protection, the battery will
start with small load in low temperature output, after temperature back to normal system can work
normally, please be patient at this time
 If the temperature is too low, it is possible that battery will be low temperature protection, at
this time, please pay attention to the working temperature range listed in the specifications of the book.
 Servicing of batteries should be performed or supervised by personnel knowledgeable about
batteries and the required precautions.
 When replacing batteries, replace with the same type and number of batteries or battery
