DELTA MAX TEST RESULTS/OBSERVATIONS:
Fast Charging from 0-100% (approximate values going into battery. Wall AC is higher because power is used to run fans, inverter, etc). You can see the wattage decreases to protect the battery cells due to heat build up.
0-80% ~ 1650W
80-92% ~ 1250W
92-97% ~ 630W
97-98% ~ 485W
98-99% ~ 300W (over 4 minutes charging drops from 485W to 300W)
@ 99% Charing drops to 250W with 2 minutes of charging left
@ 99% Charing drops to 200W with 1 minute left
100% Reached in 1 hour 45 minutes
AC inverter Output Efficiency Test - Starting at 100% Battery, with constant 200W draw to 0%:
Total AC output = 1.73KWH. 1.73 / 2.01 (battery capacity) = 86% AC output efficiency
