Inverter Battery Backup: Will It Recharge Between Power Cuts?
Wired White v1 Simulate seven days of power cuts and charging. See whether your inverter or IPS battery still covers day 3, with charger limits, charge taper and lead-acid or LiFePOâ‚„ behaviour.
Inverter Loss and Heatsink Calculator
Wired White v1 Estimate IGBT inverter losses and heatsink requirements including base spreading. Compare footprint and thickness effects on resistance and hot-spot temperature.
Battery Runtime and Backup Power Calculator
Wired White v1 Calculate battery and UPS runtime for fans, lights, TVs or boilers. Compare editable 150/200 Ah inverter examples and size battery counts from runtime, voltage and C-rate limits.
