Q1: How long can an 8000W inverter run from my batteries?
Divide the usable battery energy (in kWh) by the load (in kW), and allow for conversion losses. For example, a continuous 8 kW load draws roughly 8.7 kWh from the bank each hour at 92% efficiency. Real loads are usually lower than the maximum, so runtime is normally longer.
Q2: What DC voltage does the 8000W model use?
The standard input is 216V DC, with about 37 A of DC at full load, from a lithium or lead-acid bank. Contact us with your battery configuration if you need a different input voltage.
Q3: How much surge can it handle, and for how long?
It can deliver 150% of rated power, or 12 kW, for 5 seconds, which is intended for motor starts and similar brief peaks. Continuous loads should stay below 8000W.
Q4: Should I choose the 8000W or the 6000W model?
Compare your simultaneous load and your battery bank voltage. The 6000W model works with a 192V bank, while the 8000W model uses a 216V bank and gives two more kilowatts of continuous capacity. If your calculated load, including a margin, is close to 6000W, the larger unit provides more headroom.
