Utility Specific Adjustments

• Please try to be <15KW AC system size whenever possible. For example: Please use mix of 7.6KVA and 5.7KVA to be under 15KW AC rather than using two 7.6KVAs as long as finance inverter OD ratio is under the limit. This will avoid Level 2 application and reduce approval times. Also avoids EE stamp.
