 The invoice's grand total is UGX 4,406,000. The lines add up correctly. 
 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.
