Before You Begin: Safety First

Lithium battery inverters are generally simpler to install than traditional systems since the battery is built in, but they still involve electrical connections. We strongly recommend having a certified electrician or Lento-authorized technician handle the installation, especially for higher-capacity commercial units. Always turn off mains power before connecting any wiring, and never attempt installation in wet conditions or near flammable materials.

Step 1: Choose the Right Model for Your Needs

Before installation, confirm you have the correct model for your load requirements.

Sine wave inverter with inbuilt lithium battery

Model	Battery Voltage (VDC)	Rated Capacity (VA)	Compatible Battery Types	Typical Applications
Li-ion 1415	12.8V	1100 VA	Lithium Battery (100AH)	Household and commercial
Li-ion 2500	25.6V	2100 VA	Lithium Battery (100AH)	Commercial spaces, hybrid solar
Li-ion 3000	25.6V	2500 VA	Lithium Battery (100AH)	Commercial and household

Hybrid solar inverter with inbuilt lithium battery (off-grid — PWM)

Model	Battery Voltage (VDC)	Rated Capacity (VA)	Compatible Battery Types	Typical Applications
Li-ion Solar 1415	12.8VDC	1100 VA	Lithium Battery (100AH)	Household
Li-ion Solar 2500	25.6VDC	2100 VA	Lithium Battery (100AH)	Household
Li-ion Solar 3000	25.6VDC	2500 VA	Lithium Battery (100AH)	Household

Hybrid solar inverter with inbuilt lithium battery (off-grid — MPPT)

Model	Battery Voltage (VDC)	Rated Capacity (VA)	Compatible Battery Types	Typical Applications
Li-ion 1100VA/12V	12.8V	1100 VA	Lithium Battery	Household
Li-ion 2100VA/24V	25.6V	2100 VA	Lithium Battery	Household and commercial
Li-ion 2500VA/24V	25.6V	2500 VA	Lithium Battery	Household and commercial

Step 2: Pick the Right Placement

Install your inverter in a cool, dry, well-ventilated area away from direct sunlight, moisture, and dust. Keep at least a few inches of clearance around the unit for airflow, and avoid placing it near flammable materials or in enclosed cabinets without ventilation. Wall-mounting or placing on a stable, flat surface at a reasonable height is ideal for both household and commercial inverter installation.

Step 3: Connect the Mains Power (Input)

With mains power switched off at the source, connect the inverter's input wiring to your home or office's electrical panel according to the wiring diagram provided in the user manual. Double-check polarity and wire gauge recommendations to prevent overheating or damage.

Step 4: Connect the Load Output

Connect the inverter's output terminals to the circuits or appliances you want backed up. For a 12V lithium battery inverter, this typically covers lighter loads like lights and fans; for a 24V lithium battery inverter, you can support heavier household or commercial appliances.

Step 5: For Hybrid Solar Models — Connect Solar Panels

If you're installing a PWM or MPPT hybrid solar inverter, connect your solar panel array to the designated solar input terminals. Ensure panel voltage and current ratings match the inverter's specifications:

PWM models work well with simpler, smaller solar arrays.
MPPT models can handle a wider voltage range and extract more power from larger arrays.

Step 6: Power On and Test

Once all connections are secure, switch on the mains supply first, then power on the inverter. Check the display or indicator lights to confirm the battery is charging and the output is stable. Test with a small load before connecting your full household or commercial setup.

Step 7: Monitor Initial Charging Cycle

Allow the inbuilt lithium battery to complete its first full charge cycle before relying on it for backup power. This helps calibrate the battery management system for accurate charge level readings going forward.

Common Installation Mistakes to Avoid

Installing in direct sunlight or poorly ventilated spaces
Incorrect wire gauge causing voltage drop or overheating
Mismatched solar panel specifications with PWM/MPPT input ratings
Skipping the initial full charge cycle
Overloading the inverter beyond its rated VA capacity

Frequently Asked Questions

Q1. Can I install a Lento lithium battery inverter myself?
Basic setup steps are straightforward, but we recommend a certified electrician handle wiring connections, especially for commercial-grade or hybrid solar installations.

Q2. Where should I place my lithium battery inverter?
Choose a cool, dry, well-ventilated space away from direct sunlight and moisture, with clearance around the unit for airflow.

Q3. Do PWM and MPPT inverters install differently?
The core installation steps are similar, but MPPT inverters can accept a wider solar panel voltage range, while PWM inverters need closer panel-to-battery voltage matching.

Q4. How long does the initial lithium battery charge take?
This varies by model and capacity, but it's important to let the battery complete its first full charge cycle before regular use.

Q5. Where can I buy a Lento lithium inverter for installation?
You can order directly from Lento Industries or purchase a single unit via the Lento Amazon Store.

Conclusion

Installing a Lento inbuilt lithium battery inverter correctly — from choosing the right model and placement to proper wiring and initial charging — ensures years of safe, efficient performance. Whether it's a sine wave inverter installation for household backup or a hybrid solar inverter installation for off-grid solar power, following these steps (with professional help where needed) sets you up for reliable, eco-friendly energy backup.
