I have two AC500 units and two B300S batteries. I use the units for backup / generator power and use them in their split-phase config during a power outage for our home. Currently they connect via a generator plug with a manual switch. I have solar arrays that keep them charged. I am curious what I need to do to use them in a configuration where they provide power to the house or at least a majority of the circuits all the time in a grid-tied scenario. I assume they could provide power to everything but the main HVAC for the home most of the time.

Sorry, the AC500/AC300 is positioned as an off-grid high-power (capacity) home backup system, and it does not support grid-connected use. Currently, we have home storage systems like the EP760 (main for EU&AU) and EP900 (main for US) that support grid-tied and feed power back to the grid.
Okay, I’m not interested in feeding excess power back to the grid, only using the two AC500 units as power for my home when grid power is also available. The AC500 advertising indicates “Reduce your electric bill” and I don’t see how I could reduce my power bill if the system only works when the power is off? What is needed to have the two AC500 systems running everything like lights and freezer / refrigerator on a day to day basis?

“Reduce your electric bill” refers to achieving complete self-sufficiency by arranging solar panel arrays connected to the AC500 system, allowing for off-grid usage without the need for additional reliance on the grid (and extra electricity costs).
Regarding this issue, would you like to know what additional components are needed for the normal operation of two AC500 systems?
I would like to know what components are needed that would allow the AC500 in split phase config to run a sub panel (ProTran/2) with two 240V circuits (well pump and water heater) and several 120v circuits. I would like to confirm this configuration is compatible.
@Austin814 It is compatible .
You can buy AC500 Dual Firewire Distribution Box directly from our website, all the required components are included, and then just have your electrician connect it according to the wiring diagram.
It does not look like this unit would allow me to switch individual circuits from Bluetti Power to Utility Power? This looks like it only supports switching all circuits from backup power to grid power?
I’m curious why the AC300 home integration kit has the ability to switch each individual circuit from Generator to Grid, but the home integration kit for the AC500 does not have that feature? I would like to be able to move some circuits from solar to grid power as peak sun hours change through the year. Can I use the Reliance Pro/Tran 2 A510C with the AC500 split phase with four batteries?
- You cannot switch a single circuit from the BLUETTI power supply to the grid; the AC300 kit cannot do this either.
- You can meet this requirement by setting the machine’s time control UPS mode.
- Yes, sure.
“You cannot switch a single circuit from BLUETTI Power supply to the grid; the AC300 kit cannot do this either”
See how each circuit has its own “GEN / OFF/ LINE” switch located above the circuit. It does allow each individual circuit to be switched from LINE power to BLUETTI Power without switching all circuits. That is the feature I want for the AC500 in Split Phase mode. (Image Below)

Sorry for the confusion due to previous replies.
As confirmed by the technical team, AC300’s distribution box is indeed capable of single circuit control with more complex features than AC500’s, but AC500’s distribution box can only be controlled in its entirety.
If you want a single-circuit control distribution box for the AC500, it is recommended to purchase it separately from Reliance, while other cables can be purchased individually from BLUETTI.
Most of my house except ceiling lights is off-grid. Everything is plugged directly into the AC500 because the way my house is setup it’s easier than trying to go through the breaker box.

I set PV Priority UPS to a minimum SOC, and if it drops below that value during the night it will draw grid power. You balance out the load so it doesn’t need grid power by the time the sun comes up. You also have to plan on using appliances during the day and keep nighttime power draw at a suitable level.

I have 6 B300s batteries and there are times I could use more batteries. The only way now is to buy another AC500 and more B300s batteries and divide up the load.
