When are the batteries going to ship?

As soon as they arrive to our warehouse we will work as hard as we can to get them out immediately.  We have multiple containers of these batteries in transit, and expect to have inventory ramped up to have batteries In-stock for immediate shipment by June.

Why do you request inverter type?

A: Since the inverter is controlled by the battery, some inverters require special settings changed within the batteries.  The primary example being SMA’s Sunny Island, which require adjustments to the BMS protection parameters because it is slower to respond to the requests made by the BMS, so more conservative values must be used.  The listed inverters operate successfully in a closed-loop communication operation method.  If you are not using closed-loop communications, please select “Other”.

Will “X, Y, or Z” inverter communicate with this battery?

Current products supporting communication are all Victron equipment via a Cerbo-GX, MPP Solar inverters, Sol-Ark 5k, 8k, 12k & 15K, Certain-models of Growatt inverters, SMA Sunny Island (With appropriate setting changes).

If my inverter doesn’t communicate, can I still use this battery?

Yes, however you will need to manually set the appropriate settings within the inverter manually, and run these batteries in an open-loop, voltage control based configuration.

What is the cost to ship to my address?

Due to the weight and nature of this product, it must be shipped by Freight versus standard FedEx/UPS ground.  The shipping price is calculated based on your location during checkout. There is a base charge for the first battery, however additional batteries only add a minimal cost. If our shipping charge is above the actual cost, we will issue a refund.

Can you ship to Hawaii/Alaska/Canada?

For shipping to Hawaii/Alaska/Canada, you must setup your own freight forwarder; we can ship to their warehouse but you must setup and cover all costs associated with freight forwarding.

Can I pickup from your warehouse?

For the safety of our team, we do not allow local pickups; Initially being in Las Vegas we attempted to offer this, however, we’ve had some rather questionable figures attempt pickup that risked the safety of our staff.  For this reason, we do not allow local pickups anymore.
