Recharging with solar

The Vtoman FlashSpeed 1500 accepts up to 400W of solar input. In real conditions that harvests about 1.5 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.

Solar can keep up. An aquarium heater (100W) uses about 960Wh a day at 24 hours of use, so with enough panels and good sun the Vtoman FlashSpeed 1500 can run it indefinitely.

Tips

  • Aquarium heaters cycle with their thermostat. Add an air pump (5–10W) to keep fish oxygenated during an outage.
  • You’ll still have about 1400W of AC capacity left for other devices at the same time, though they’ll share the same battery.
  • The Vtoman FlashSpeed 1500 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
