Good Day. My name is Sara. My husband Todd bought the 48v 400ah batteries from your business. Unfortunately he hasn’t have time to communicate with you, but we’re having troubles with the batteries charging. He spoke to your people a few days ago and you helped him to connect the batteries to the inverter and we are now getting power. The problem now is the batteries are not getting charge from the solar panels and the batteries are draining. Good thing is the percentage is going slow and not fast. Question is: What do we need to do to charge the batteries? Your help is always appreciated.
