PGEM PRO battery guide

Choosing PGEM PRO for your system

PGEM PRO provides 14.3kWh of nominal storage in a 51.2V LFP battery module. For a Nigerian home or small business, choose capacity from the loads you want to keep running and the hours you need them.

PGEM or PGEM PRO?

Two low-voltage battery options for home backup
What to compare	PGEM	PGEM PRO
Nominal energy per module	5.12kWh	14.3kWh
Rated voltage	51.2V	51.2V
Rated capacity	100Ah	280Ah
Selection focus	A smaller amount of stored energy per module	More stored energy per module for a larger backup requirement

At the same load and usable-energy settings, a larger battery stores more energy for backup. The right choice also depends on available discharge power, inverter compatibility and installation space. Compare the PGEM 5.12kWh battery if your storage requirement is smaller.

What 14.3kWh means for backup power

Energy: how much is stored

The 14.3kWh figure is nominal capacity. Energy available to your appliances depends on the permitted depth of discharge, reserve setting, temperature, battery condition and inverter losses.

Power: what can run together

The battery's continuous current limit and the inverter's output limit both matter. An appliance with a motor may draw more power when starting than while running.

Estimate runtime from usable energy and average load. Lights, internet equipment and a refrigerator have a different daily profile from air conditioning or a pump. Send a load schedule for a system recommendation; capacity alone cannot establish how long the whole home will run.

See our inverter battery sizing and runtime guide for the planning method.

Matching PGEM PRO to your inverter

Our Nigeria installation records include PGEM PRO with SNA 6K and SNA-EU 12K inverters. Before choosing a new combination, confirm the inverter's battery voltage range, charge and discharge limits, BMS protocol and firmware.

For an existing system, send clear photos of both equipment labels. Compatibility with a brand does not mean every inverter from that brand is compatible.

PGEM PRO is a low-voltage battery. It is not interchangeable with PSTACK high-voltage storage, even when two systems have similar kWh capacities.

The records document installed equipment. They do not establish a fixed backup duration or energy saving for another home.

Planning more battery capacityOne, two or more modules need a matched system design

1 module14.3kWh nominal

2 modules28.6kWh nominal

3 modules42.9kWh nominal

The capacity totals are arithmetic examples, not pre-approved packages. The published PGEM PRO range supports up to 32 units in parallel without an additional expansion device, subject to the supplied revision and approved design. Cabling, isolation, protection and suitable installation space are still required.

Before adding batteries later, have the installer review the existing modules, state of health, firmware, BMS configuration and inverter limits. More stored energy does not automatically increase AC output.

Indoor installation and local supportPlan access, mounting and the information needed for a quote

PGEM PRO has an IP20 enclosure. Choose a dry indoor position with suitable support, ventilation, cable routing and maintenance access. Check the supplied model's dimensions and weight before deciding on floor or wall mounting.

For a battery quotation, send the inverter model, required backup hours, appliances, location and any existing battery details. Ask whether mounting, protection, cabling, delivery and commissioning are included.

For after-sales help, keep the serial number, installation record and any fault screenshots ready. Visit warranty support or contact the Nigeria team.

Frequently asked questions

Is PGEM PRO 14.3kWh the energy available to my appliances?

14.3kWh is the nominal energy rating. Usable energy depends on depth of discharge, reserve settings, temperature and battery condition; inverter losses further affect energy delivered to AC appliances.

Can PGEM PRO work with my existing inverter?

Confirm the exact inverter and battery models, voltage range, continuous current limits, BMS protocol and firmware. A listed brand or a matching voltage alone does not establish compatibility for every model.

Can I add more PGEM PRO batteries later?

Expansion is possible only after checking the supplied revision, existing battery condition, firmware, communication, current sharing and protection. Have the installer approve the complete configuration before adding modules.

Can PGEM PRO be installed outdoors?

PGEM PRO is rated IP20 and needs a suitable dry indoor location. For a different installation environment, compare an appropriately rated battery and follow its model-specific installation requirements.

What is the PGEM PRO warranty and cycle rating?

PGEM PRO has a 10-year warranty and a 6000-cycle rating. Cycle life depends on operating conditions and is not a guaranteed number of backup hours. Request the written warranty terms for your supplied unit.

What should I include in a PGEM PRO quote request?

Send your city, inverter model, appliance list, target backup hours and existing battery details. Ask the quotation to identify delivery, mounting, cables, protection and commissioning as well as the battery.
