Reduced Installation Time & Cost

The battery cabinet comes pre-assembled with dual-entry side-doors and pre-drilled mounting holes, so you can install the inverter and batteries in minutes.

Scalable & Expandable

Its easy to start with a smaller battery bank and expand if your energy needs change. Connect cabinets together and parallel up to 64 battery modules.

Saving (Wall) Space

Mount the inverter directly onto the battery cabinet. This gives you more choices on where to place your battery system while avoiding installing equipment on your walls.

SR5K-UL Battery Module

51.2VDC | 100Ah | 5.12 kWh

The SR5K-UL battery module has a 5 kWh energy capacity designed for daily use. An advanced battery management system (BMS) optimizes and protects the battery, while communicating with other connected batteries and the inverter. Battery modules are designed for plug & play installation with all KLL Energy battery cabinets and allow for simple expansion of your battery bank at any time.

Welcome to the Future of Home Energy

The US electric grid is deteriorating, with increasing blackouts and electricity costs surpassing inflation. A sustainable solution for reliable and affordable energy is to become grid-independent by converting your home into a microgrid. This setup allows you to generate (using solar panels), store, and use your own energy (with battery storage), freeing you from high energy bills, rising electric rates, and unexpected outages.

During the Day

The solar energy you produce powers your home and charges your batteries. When your batteries are fully charged, any extra solar is exported to grid.

At Night

The solar energy you produce powers your home and charges your batteries. When your batteries are fully charged, any extra solar is exported to grid.

Battery Sizing

Why you need more storage than you may think

We want all customers to have a great battery system that will perform as expected for years and years to come - that means proper battery sizing. With KLL Energy systems, getting the battery sizing correct from the start isn't as important as other systems since it's simple to add more batteries and cabinets at any time. However, it can be frustrating when you find out months or years later that you need more batteries than you first thought. Here are some important considerations when sizing your battery system and why you may need more batteries.

Depth of Discharge

If a 5 kWh batteries discharges 80% of its energy (4 kWh), then the depth of discharge (DOD) is 80%. Even though batteries can discharge to 100%, it is not recommended. Deeper discharging (>90%) can damage the battery cells and reduce the battery life. Best practice for daily battery cycling is 80% DOD, so you should you increase your battery bank size by 20% if you want your batteries to last >15 years.

Natural Capacity Loss Over Time

As batteries charge and discharge, it is natural to gradually lose some storage capacity. For example, SR5K-UL batteries will lose 20% capacity after cycling 6000 times (80% retained capacity after 6000 cycles). Consider adding 20% additional battery storage to account for these natural loses over time.

Energy Demand Expected to Increase

Energy demand in the US is expected to increase over 30% by 2050. A big factor is electric vehicles (EVs). If you plan on adding an EV or additional energy loads to your home in the future, then consider increasing your battery storage to account for it.

Quickly Sizing Your Home Battery System

A common question we get from homeowners, business owners and installers is how much battery storage does a project need. Here is the quick formula we use to size battery systems.

Peak Shaving (Essential Backup)

If you are looking for a battery system to eliminate the expensive peak times (5 to 8 pm) and/or provide essential home backup, then a simple way to calculate your battery storage is size to take you daily average kWh use (refer to your electric bill) and divide in half. For example, if your average daily use is 30 kWh, then your battery storage size would be 15 kWh. This takes into consideration the factors mentioned in "Why you need more battery storage than you may think", listed above.

>85% Grid Independence (Partial Off-Grid)

This is our most commonly recommended battery storage size for homeowners. With adequate solar, this battery system size is designed to reduce your annual grid energy by >85%, which drastically reduces electric bills and helps avoid utility rate hikes, while also providing home backup.

Size the battery storage equal to your daily average kWh use. For example, if your daily average is 30 kWh, which is the US average, than your battery storage size would be 30 kWh. This takes into consideration the factors mentioned in "Why you need more battery storage than you may think", listed above.

Off-Grid

For off-grid living, it is recommended to size your battery based on 2-3x your average daily use. For example, if your daily average kWh is 30 kWh, then your recommended battery storage size would be 60 to 90 kWh.
