We have been successful with double and triple Sol-Arks being able to start just about any single phase loads, the imbalance tolerance is multiplied per inverter.
Like others we had numerous single inverter sites having issues offgrid, primarily while completing construction, chop saws and air compressors being the main culprits. We measured a max surge amp as high as 60a for a 1hp compressor and large chop saw. We have been successful in using an Outback X240 balancing transformer to resolve the bus unbalance shut downs. Does anyone know of a non outback balancing transformer available on the market? > Sent from a IPhone, with touch screen keys on the fly.
