Technical FAQs 4

How many lithium batteries can a hybrid inverter stack?

Stack up to 9 Lithium Batteries per system! Just give our office a call and ask about adding more power storage. Delivering 10,000W of rated power output, this rugged pure sine wave hybrid inverter is capable of pairing with either GEL or LI batteries. Dual MPPTs provide 99% efficiency. Provides 120V and 220V output power.

How much solar can a 20 foot container hold?

20 foot containers can expand from 3,000W of solar up to 6,000W. 40 foot containers can expand from 3,000W up to 12,000W of solar in the future. We love the strategically placed solar panels on top of the container roof - we've accomplished this secure mounting with our field tested RPS Scalable Ground Mount.

Which battery bank should I choose for the Instant off-grid containers?

Choose between a GEL Deep Cycle Sealed Lead Acid battery bank or a next-gen Lithium Iron bank. See below from more details and pictures. Pre-configured by RPS engineers. 370W solar panels power the Instant Off-Grid Containers. Each panel measures 69.1”×40.9”×1.4”.

What is LZY solar storage?

LZY offers large, compact, transportable, and rapidly deployable solar storage containers for reliable energy anywhere.
