Not on the invoice
- PV cable. The earlier quote (4,426,000) included 30 m of 6 mm² cable at 360,000. This one does not, so the cable is bought separately (the 4 mm² cable was out of stock).
- Installation labour. The line is blank (labour via Green Volta, separate).
- VAT. The 18% line is blank, so VAT on the invoice is not shown.
Changes from the earlier quote (7 Oct)
- The 2-pole 32 A 500 V DC breaker (80,000) became a 32 A 4-pole DC isolator (320,000). For a single string of 8 panels (Voc about 422 V, about 437 V cold) a 2-pole device rated for the voltage is normally enough; a 4-pole isolator is often wired as two poles in series for extra breaking capacity. Worth confirming what was intended.
- The 1000 V surge protector (150,000 earlier) is now 110,000.
- Delivery is a separate line (100,000).
Terms (from the invoice)
- Warranty: 10 years on panels; 1 year manufacturing defect warranty on the rest, on a back-to-base basis. No warranty against misuse, surges or acts of God.
- Title of goods stays with Muden Systems until fully paid.
- Validity: 15 days or until stock runs out.
To do on delivery
- Check every line against this table, including panel count and rating.
- Take photos of labels (panel model, serials) for the warranty record.
- Confirm cable, labour and VAT with the supplier and the installer.
