Installation & Engineering Notes

Professional installation is strongly recommended because this system combines two hybrid inverters, two high-capacity lithium batteries and a 12.6kWp PV array.

The 28 solar panels should be installed in a structurally suitable, unshaded location with correct orientation and string configuration. Appropriate PV isolators, breakers, surge protection, earthing and AC distribution protection should be incorporated.

The inverters and batteries should be installed in a dry, secure and adequately ventilated location. High-starting-current appliances must be assessed before connection.

Macire can provide technical guidance on system configuration, protection, cabling and load distribution.

Care, Maintenance & Operations

• Keep all 28 solar panels clean and free from excessive dust and debris.
• Inspect panel mounting structures periodically.
• Maintain adequate ventilation around both hybrid inverters.
• Keep lithium batteries protected from water and excessive heat.
• Regularly monitor battery state of charge and system performance.
• Avoid sustained loads exceeding the configured inverter capacity.
• Periodically inspect electrical protection and cable connections.
• Contact Macire for technical support, servicing guidance and compatible components.
