16 kWh Building Block
Each battery provides 16 kWh of rated storage. That makes it straightforward to build larger systems without using a large number of small individual battery modules.

UZ Energy IG-16K-U 16 kWh Battery Storage
Why Palm Tree Energy uses the UZ Energy IG-16K-U for off-grid, whole-home backup and hybrid energy systems.
The battery is one of the most important components of an off-grid or backup-power system. Capacity matters—but so do power capability, expandability, inverter compatibility, installation flexibility and the ability to support the property as its energy requirements change.
Palm Tree Energy uses the UZ Energy IG-16K-U as one of our battery-storage options because its 16 kWh architecture gives us a practical building block for designing residential, rural and off-grid energy systems.

More Than a Battery
Battery selection affects the performance of the entire energy system.
A battery should not be selected simply because it has a large kilowatt-hour number. The battery must work with the inverter, support the electrical loads, accept available solar and generator charging power, and provide enough stored energy for the property’s operating requirements.
Palm Tree Energy looks at the battery as part of the complete energy infrastructure. We evaluate solar production, inverter capacity, generator capacity, electrical loads, expected overnight consumption, seasonal conditions and future expansion before determining how much battery storage makes sense.
What We Consider When Selecting Battery Storage
✓
Required stored energy in kilowatt-hours
✓
Continuous and peak power requirements
✓
Hybrid inverter compatibility
✓
Available solar charging capacity
✓
Generator charging and off-grid operation
✓
Future solar and battery expansion
✓
Equipment location and installation conditions
Why We Use This Battery
Why the UZ Energy IG-16K-U fits many Palm Tree Energy systems.
The IG-16K-U provides a combination of storage capacity, power capability and scalability that allows us to configure battery systems around the actual requirements of the property.
02
Substantial Power Capability
Energy capacity tells us how long a battery can supply power. Power capability tells us how much load it can support at one time. The IG-16K-U is designed to provide substantial charge and discharge capability in addition to energy storage.
03
Expandable Architecture
Storage can be configured around the initial project requirements while preserving a path for additional capacity as electrical loads, solar production or backup-duration requirements increase.
04
51.2 V Low-Voltage Platform
The 51.2 V architecture works with the type of low-voltage hybrid inverter and off-grid systems Palm Tree Energy commonly designs and integrates.
05
Off-Grid Applications
Battery storage is especially important on properties where solar and generator power must work together. Stored energy allows the house to operate without requiring the generator to run continuously.
06
Long-Term System Planning
We prefer equipment that allows the energy system to evolve. A properly planned battery platform can remain part of the system as additional solar, loads or generating capacity are added.
Scalable Energy Storage
Build the battery bank around the property.
The 16 kWh battery format gives us a practical way to increase storage capacity as the energy requirements of a project increase.
16 kWh
1 Battery
A single 16 kWh storage module for applications where the load analysis supports a smaller battery bank.
32 kWh
2 Batteries
A useful configuration for projects requiring substantially greater overnight or backup energy.
48 kWh
3 Batteries
Additional capacity for properties with larger loads, longer backup requirements or greater solar production.
64 kWh
4 Batteries
Larger energy-storage capacity for demanding residential, rural and off-grid applications.
Battery Protection & Cold-Weather Operation
Designed for demanding energy-storage installations.
Battery storage equipment may be installed in very different environments. Palm Tree Energy considers temperature, equipment location, protection features and operating conditions when designing the battery portion of an energy system.
Fire Protection
Available Fire-Extinguishing Protection
The IG-16K-U platform is available with a fire-extinguishing device, adding another layer of protection within the battery system. This is an important feature to consider when planning battery storage for residential, rural, off-grid and equipment-room installations.
Cold-Weather Operation
Available Internal Battery Heating
The IG-16K-U is available with an internal heating configuration for cold-weather applications. The heating system allows the battery to support charging at temperatures down to approximately −20°C (−4°F), making the platform useful for colder climates and installations where winter temperatures can otherwise restrict lithium-battery charging.
Battery Sizing
More battery is not automatically better. The system has to work together.
Battery capacity must be considered alongside solar production. A large battery bank provides additional reserve capacity, but the available solar array must still produce enough energy to recharge it.
In an off-grid system, a generator can provide additional charging when solar production is reduced by weather, seasonal conditions, shading or nighttime operation.
This is why Palm Tree Energy evaluates the complete system rather than treating the solar array, batteries, inverter and generator as separate pieces of equipment.
SOLAR
Produces the energy.
Solar supplies property loads and charges the battery bank whenever
sufficient sunlight is available.
BATTERY
Stores the energy.
Stored energy supplies the property when solar production is
insufficient or unavailable.
INVERTER
Manages and converts the power.
The hybrid inverter coordinates solar, batteries, electrical loads,
utility power when present and generator operation.
GEN
Provides supplemental energy when needed.
On an off-grid property, the generator can recharge the batteries when
solar production cannot maintain the programmed battery reserve.
Complete Energy Infrastructure
The battery is one part of a complete power system.
Palm Tree Energy designs the equipment to operate together rather than simply assembling individual components.
Energy Source
Solar Array
Produces renewable energy for immediate electrical loads and battery charging.
Energy Storage
UZ Energy Battery
Stores available energy so the property can continue operating when solar production drops.
Energy Management
Hybrid Inverter
Coordinates solar production, battery charging, electrical loads and generator operation.
Supplemental Power
Generator
Provides additional energy and battery charging during extended periods of insufficient solar production.
