Bull points
- we've got a product that can do it, that's proving itself every day out in the field, that customers are coming to us
- We feel good about the pipeline. We have the relationships we're building on
- we ended the quarter with $645 million in backlog, representing 2.6 gigawatt hours of storage after converting $57 million to revenue in the quarter.
Bear points
- Revenue was roughly flat quarter over quarter as project mix shifted with more cubes being delivered, while AC scope, including things like transformers and inverters, has decreased.
- customer site readiness delayed some of this revenue into future periods.
- Material cost is up 4% year over year. That is the cost of transitioning from the prior BMS to Don OS in the middle of last year.
