Reading the specifications

Fronus LD 52 5.12kWh Lithium Ion Battery 51.2V 100Ah is listed with 4 published specifications from Fronus, including nominal voltage of 51.2 V, capacity of 100 AH / 5.12 kWh, compatibility of 48V solar systems and cycle life of 6,000 to 8,000 life cycles. Those figures are what decide whether this unit fits your system, so read them against the equipment it will connect to before comparing price.

For a battery, the figures that matter most are 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, 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. 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.

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.
Size from your evening consumption. Add up what actually runs after sunset for the hours you want covered, then divide by the usable capacity per unit — that number, not the array size, sets how many batteries you need.
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.
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.

Common mistakes

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.
Sizing the bank for total daily consumption rather than after-dark consumption, which typically doubles the cost for no benefit.

Price and availability

Fronus LD 52 5.12kWh Lithium Ion Battery 51.2V 100Ah is listed at ₨ 185,000 (PKR). 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 Fronus locally before ordering.

Fronus LD 52 5.12kWh Lithium Ion Battery 51.2V 100Ah — frequently asked questions

How much does Fronus LD 52 5.12kWh Lithium Ion Battery 51.2V 100Ah cost?

Fronus LD 52 5.12kWh Lithium Ion Battery 51.2V 100Ah is listed at ₨ 185,000 (PKR). 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.

What are the specifications of Fronus LD 52 5.12kWh Lithium Ion Battery 51.2V 100Ah?

We hold 4 published specifications for this battery, including nominal voltage 51.2 V, capacity 100 AH / 5.12 kWh, compatibility 48V solar systems and cycle life 6,000 to 8,000 life cycles. The full table is on this page.

Who makes Fronus LD 52 5.12kWh Lithium Ion Battery 51.2V 100Ah?

Fronus LD 52 5.12kWh Lithium Ion Battery 51.2V 100Ah is a Fronus product, listed under batteries. The Fronus brand page lists the rest of its range so you can compare across the catalogue.

Is Fronus LD 52 5.12kWh Lithium Ion Battery 51.2V 100Ah right for my system?

That depends on what it has to connect to. For a battery, check nominal capacity in ampere-hours (Ah) or kilowatt-hours (kWh), usable capacity after depth of discharge — LiFePO4 typically allows 80–100%, lead-acid closer to 50% and system voltage: 12 V, 24 V and 48 V for low-voltage packs, or a high-voltage stack against the rest of your equipment before price enters the decision. 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.

Where can I buy Fronus LD 52 5.12kWh Lithium Ion Battery 51.2V 100Ah?

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.
