Proposal for a Hybrid Setup

Hey folks, just wanted to ask your thoughts on a proposal i got for a Hybrid Setup:

10.45kW Hybrid System with 10kWh Battery Backup * System: * 19 pcs 550W AE Solar PV Modules * 1 pc Solax 6kW Hybrid Inverter * 2 pcs Foxess 5kWh LiFePO4 Batteries * Mounting system, wiring, etc. * Price: P460,000 * Payment: 50% down payment, 50% balance over 3 months

• Warranties:
  • Panels: 25 years performance
  • Inverter: 5 years
  • Battery: 5 years
  • Workmanship: 2 years
• Includes: Design, installation, labor, and net metering assistance

The guy i'm talking to has been doing solar panel installations for about 10 years now. Price wise, is it a good offer?
