What these specifications mean

Detailed specifications for LG 16H Prime High Voltage Battery | 16kWh | 400V | Stackable | IP55 | 10-Year Warranty have not been published yet. LG lists this battery in the Batteries, and we add fields as the manufacturer releases them — in the meantime, ask your distributor for the datasheet before ordering.

For a battery, the figures that matter most are usable capacity after depth of discharge — LiFePO4 typically allows 80–100%, lead-acid closer to 50%, system voltage: 12 V, 24 V and 48 V for low-voltage packs, or a high-voltage stack, continuous charge and discharge current, which limits how much power you can draw from the pack and cycle life at a stated depth of discharge, commonly 3,000–6,000 cycles for LiFePO4. Storage is what turns a solar array from a daytime bill-reducer into a system that covers evening loads and rides through outages. It is normally the single most expensive component, so sizing it correctly matters more than with any other part.

Before you buy a battery

The checks below apply to any battery. Run them against the specification table above — most disappointing solar purchases are compatible-on-paper units that fail one of these in practice.

Match voltage to the inverter, and confirm the battery appears on the inverter maker's supported list. Closed-loop communication lets the inverter respect the battery's real charge limits instead of guessing.
Read the warranty in full: lithium warranties are stated as a term plus either a cycle count or a total energy throughput, and whichever limit arrives first ends the cover.
Leave room to expand. Packs that parallel cleanly let you add capacity later; ones that do not force a full replacement.
Compare usable kilowatt-hours, not nameplate capacity. A 100 Ah lead-acid battery at 12 V is nominally 1.2 kWh but only about 0.6 kWh is safely usable, while a 100 Ah LiFePO4 pack gives you roughly 1.0–1.2 kWh.

What people get wrong

Installing lithium packs in an unventilated, hot enclosure. Sustained high temperature is the fastest way to lose cycle life.
Ignoring the charge current limit and pairing a large array with a small bank, which trips protection and shortens life.
Mixing old and new batteries, or different chemistries, in one bank. The weakest unit drags the whole bank down and can be damaged by the others.

Price and availability

LG 16H Prime High Voltage Battery | 16kWh | 400V | Stackable | IP55 | 10-Year Warranty is listed at $ 2,750 (USD). Solar pricing moves with supply, import duties and exchange rates, and distributors set their own margins, so treat this as a comparison reference and confirm the current figure before you order.

SolarBazaar compares equipment rather than selling it. Shortlist here on specification and price, then buy from an authorised distributor or installer in your country: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports LG locally before ordering.

LG 16H Prime High Voltage Battery | 16kWh | 400V | Stackable | IP55 | 10-Year Warranty — frequently asked questions

How much does LG 16H Prime High Voltage Battery | 16kWh | 400V | Stackable | IP55 | 10-Year Warranty cost?

LG 16H Prime High Voltage Battery | 16kWh | 400V | Stackable | IP55 | 10-Year Warranty is listed at $ 2,750 (USD). The figure is indicative — solar prices move with supply, duties and exchange rates, and each distributor sets its own margin — so confirm the current price with a supplier before ordering.

Who makes LG 16H Prime High Voltage Battery | 16kWh | 400V | Stackable | IP55 | 10-Year Warranty?

LG 16H Prime High Voltage Battery | 16kWh | 400V | Stackable | IP55 | 10-Year Warranty is a LG product, listed under batteries with model reference 1652001. The LG brand page lists the rest of its range so you can compare across the catalogue.

Is LG 16H Prime High Voltage Battery | 16kWh | 400V | Stackable | IP55 | 10-Year Warranty right for my system?

That depends on what it has to connect to. For a battery, check continuous charge and discharge current, which limits how much power you can draw from the pack, cycle life at a stated depth of discharge, commonly 3,000–6,000 cycles for LiFePO4 and round-trip efficiency, around 90–95% for lithium and 75–85% for lead-acid against the rest of your equipment before price enters the decision. Check the continuous discharge rating against your inverter. A battery that stores plenty of energy but can only deliver 50 A cannot support a large inverter at full output.

Where can I buy LG 16H Prime High Voltage Battery | 16kWh | 400V | Stackable | IP55 | 10-Year Warranty?

SolarBazaar lists and compares equipment rather than selling it. Use the specifications and price here to shortlist, then buy through an authorised distributor or installer — buying in-channel is what keeps the manufacturer's warranty valid.
