Bluetti
The Bluetti AC500 + B300S is an overpowered modular system: 5000 W AC output, 3072 Wh per B300S battery, expandable to 18.4 kWh with 6 modules. 3000 W solar input. For those who need massive capacity and raw power.
The Bluetti AC500 + B300S is the most powerful system in this selection. The AC500 is a 5000 W pure sine wave inverter (10000 W surge) with no built-in battery: you need at least one B300S module (3072 Wh, LiFePO4) to operate. You can stack up to 6 B300S modules for a colossal 18.4 kWh capacity.
With 3000 W MPPT solar input (150-500V), recharging is fast even for massive setups. The inverter also offers UPS functionality with switchover in under 20 ms. This is a system that can power an entire house during an outage: fridge, space heater, power tools, all simultaneously.
The AC500 alone weighs about 30 kg, and each B300S adds roughly 38 kg. The complete system with one battery totals about 68 kg. This is clearly a floor system, not something you hang on a wall.
The limitations mirror the EP500: no smart meter, no dynamic grid injection, no IP rating. It's not a plug & play balcony solar self-consumption system. It's a backup and energy independence solution for those who want to go big, with a budget to match.
