i recently had Cyber Power installed for my parents (with 2 Volta batteries: 175 AH). i chose to have one phase of the house connect to CyberPower. Any suggestions/comments to improve ? There is a common ground and the output coming from the inverter is only hot wire. This model of Cyber Power does not have a voltage regulator. Is it recommended to get a stabilizer ?
Also, i have noticed that the fan slows down a bit once running on the batteries. Wapda seems to supply 250V and Cyber Power supplies 220V. Could this explain the slowing down ?
