Recharging with solar
The Bluetti AC200MAX accepts up to 900W of solar input. In real conditions that harvests about 3.4 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 Bluetti AC200MAX 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 2100W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The Bluetti AC200MAX uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
