First, the trickle chargers must be UL rated if they are active while the cart is connected to AC power. And they should be appropriately fused to protect the wiring to the cart battery. Since Chargers 2 and 3 effectively become trickle chargers when their batteries are full, separate trickle chargers aren't really needed anyway. Chargers 2 and 3 should be connected to AC power when it is available, and switched over the inverter output when AC power is not available.

Second, the connection shown as a red line across the top center of the diagram indicates direct connection of the inverter output to an AC power cord. This is generally not a good idea, and in any case it provides no benefit to your cart that I can see. Powering the inverter from the cart battery and then powering Charger 1 from the inverter to charge the cart battery -- well, that arrangement has power chasing its own tail! The inverter should provide power to AC devices when AC power connection is not available, and should not be connected to Charger 1.
