≈ 2.4 days (24h/day)
System standby power: 16W (59.7% of total draw)
Provides 4× CEE 7/3 (230V) (120V 60Hz).
Pure sine wave inverter output. Safe for all standard household appliances.
Inductive motor/compressor load with 1.5× starting surge (motor inrush) (99.7% worst-case surge margin).
Wall AC fast charge at up to 1400W (70m to 80%, 95m to 100%).
Safe envelope verified: Starting surge (15W) remains comfortably below the 4400W surge trip line, with steady-state operation settling into the safe continuous zone at 10W.
About 57 hours on AC power, with the Wi-Fi router averaging 10 W (Wi-Fi 6 router plus fiber ONT or cable modem (10 W)). The Pecron E1500LFP then draws about 27 W from its battery, including 16 W for the inverter itself. Best case: about 68 hours (standalone dual-band Wi-Fi 6 router (6 W)). Worst case: about 43 hours (tri-band router plus DOCSIS 3.1 cable modem under heavy load (18 W)).
Yes. Using the 12 V DC car-socket to 5.5×2.1 mm (DC5521) barrel cable on the Pecron E1500LFP's 12 V car socket, the Wi-Fi router runs about 6.6 days instead of 57 hours on AC, 174% longer, because it skips the inverter's conversion loss and its 16 W idle draw.
That simple division gives 6.4 days, but the Pecron E1500LFP's inverter draws about 16 W whenever its AC outlets are on. At this light load that's 60% of everything the battery supplies, and inverter conversion losses take a further share. The idle figure comes from Pecron.
On wall power: about 70 minutes to 80% and 95 minutes to full (Pecron figures). With its maximum 700 W of solar input connected, expect about 560 W in full sun, so a full recharge takes roughly 2.9 hours of full sun, so it can refill in a single day with 4 peak sun hours.
It can act as a backup supply: with the Wi-Fi router plugged into the Pecron E1500LFP and the Pecron E1500LFP plugged into the wall, it switches the Wi-Fi router to battery in about 20 ms when the grid fails (Pecron calls this EPS mode).
