Audit the load before pricing equipment
List the appliances, machines, lights, routers, computers and other loads that must stay on. Separate essential loads from nice-to-have loads so the system is not oversized or underpowered.
Battery choice affects the real experience
The inverter rating matters, but battery capacity and health determine how long the system can carry the business. Runtime expectations should be realistic and based on actual use.
Plan maintenance from day one
Solar and inverter systems need clean installation, proper ventilation, monitoring and periodic checks. A good installation is an operational system, not just equipment delivery.
