[QUOTE="binky, post: 448538, member: 490"] Now, I know we have discussed VO units before, but I have a customer who may benefit from one of these units. Basically his grid supply is running at 253V, Western Power have agreed to drop this by 2.5% after monitoring the grid for a week. The customer has single phase supply for his small swimmimg pool, he has air souce heat pump, heating for water and few other pumps running off the same supply. Apparently WPD found that his power surges are hitting just over 100Amps at certain times. I was considering fitting a 100Amp VO unit, suppossed to be good for pumps and energy savings, and to drop gird voltage down further, however if I drop the voltage, is this likely to mean the current drawn increases, increasing risk of blowing his main fuse? Your opinions please. [/QUOTE]
