About the certification:
The SK48v100 has been tested by Intertek Laboratories and has been tested to conform to UL 1973 standards. The draft testing report is available here and a final version of this report will be posted soon (Approx. Mid October).
Why is UL listing important?
Local AHJ’s (authority having jurisdiction) have began adopting 2017 NEC that requires batteries and energy storage system to be listed. This excludes non-listed packs from being used in a system that is code-compliant (permitted). Now that the SK48v100 is listed to UL standards, it can be used in a system that is permitted, inspected and insured.
Often times insurance providers will deny a claim for damage if an unlisted system is involved in a claim, even if the unlisted system is not the cause of such claims.
About the packs already shipped and installed:
The certification to UL1973 standards utilizes the same hardware that the SK48v100 has used since its initial conception, therefore, existing equipment conforms to the requirements for UL1973. If you have these initial packs that do not bear the “Conforms to UL1973 standards” label, then you may contact us for these labels.
In stock while supplies last.
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?
Supports communication with MPP Solar inverters (LV6548 and LVX6048) , 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?
Yes, pickups in our Mount Pleasant UT warehouse are acceptable
