Description
60V 20Ah Commercial Bess Cabinet: overview
The OSM 60V 20Ah Commercial Bess Cabinet is a 60 V / 20Ah rated commercial and industrial battery energy storage system, storing about 1.2 kWh of nameplate energy. It is engineered for peak shaving, solar self-consumption, backup power and microgrid projects.
LiFePO4 (lithium iron phosphate) chemistry is the reference choice for this duty because it is thermally stable, keeps a flat voltage curve across most of the discharge, and tolerates daily deep cycling without the capacity walk-down that lead-acid suffers. The system is assembled around Grade A cells and managed by a battery management system that enforces the published voltage, current and temperature limits from the factory.

Sizing this commercial and industrial battery energy storage system for your project
60V 20Ah Commercial Bess Cabinet stores 1.2 kWh per system. For a rough bank size, multiply by the number of units: 1 unit ≈ 1.2 kWh, 4 units ≈ 4.8 kWh, 8 units ≈ 9.6 kWh, 16 units ≈ 19.2 kWh. Confirm the parallel limit and the inverter charge current before you finalise the string.
System voltage. This is a 60 V unit, so it matches the 48 V / 51.2 V class of hybrid and off-grid inverters and can sit on the same DC bus as other modules of the same voltage class.

Send the target specification and the artwork, and the engineering team returns a drawing and a quotation.
Frequently asked questions
How long does this commercial and industrial battery energy storage system last?
The published cycle life is ≥2000 cycles to 85%DOD. At one full cycle per day that is well over ten years of service, and the usable life is normally limited by the depth of discharge and the operating temperature rather than by the cells themselves. Keep the pack inside its published temperature window and let the BMS manage the charge profile.
What chemistry does this commercial and industrial battery energy storage system use?
It uses lithium iron phosphate (LiFePO4 / LFP) cells with a nominal rating of 60 V / 20Ah. LFP is chosen for this duty because it is thermally stable, holds a flat voltage curve for most of the discharge and tolerates daily deep cycling far better than lead-acid or NMC.
How much energy is that in practice?
The nameplate energy is about 1.2 kWh per system. Usable energy is a little lower because most systems do not go to a full 100% depth of discharge — 90% is the usual planning figure, and that is what to use when you size the bank against daily consumption.
Can it be integrated with a third-party inverter?
Yes. Tell us the inverter model and we will confirm the communication protocol and the charge profile settings before you order, so the battery and the inverter agree on voltage limits and current limits from day one.
Do you supply samples and OEM branding?
Yes. OSM supplies single units and samples, and offers OEM/ODM on the enclosure, the label, the nameplate and the packaging. Send the artwork and the target specification and we will return a quotation with the lead time.
How is it shipped and what documents come with it?
Shipments go out as Class 9 dangerous goods with the UN38.3 test summary, the MSDS and the transport documents, packed for sea or air freight. Bulk orders can be consolidated so the container is loaded to suit your warehouse.
