How to read this datasheet
Fronus TP LD 51 5.12kWh Lithium Ion Battery 51V 100Ah is listed with 11 published specifications from Fronus, including operation temperature of Charge: 0 ~ 55°C, Discharge: -20 ~ 55°C, nominal voltage of 51.2 V, storage temperature of -20 ~ 30°C (12 months), 30 ~ 60°C (6 months) and communication of CAN / RS485. 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 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%, system voltage: 12 V, 24 V and 48 V for low-voltage packs, or a high-voltage stack and continuous charge and discharge current, which limits how much power you can draw from the pack. 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.
A solar battery stores the energy your panels generate during the day so it can be used after sunset, during a power cut, or whenever grid electricity is most expensive.
What to check before ordering
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.
- 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.
- 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.
Where buyers lose money
- Sizing the bank for total daily consumption rather than after-dark consumption, which typically doubles the cost for no benefit.
- 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.
Price and availability
Fronus TP LD 51 5.12kWh Lithium Ion Battery 51V 100Ah is listed at ₨ 195,000 (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 TP LD 51 5.12kWh Lithium Ion Battery 51V 100Ah — frequently asked questions
How much does Fronus TP LD 51 5.12kWh Lithium Ion Battery 51V 100Ah cost?
Fronus TP LD 51 5.12kWh Lithium Ion Battery 51V 100Ah is listed at ₨ 195,000 (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 TP LD 51 5.12kWh Lithium Ion Battery 51V 100Ah?
We hold 11 published specifications for this battery, including operation temperature Charge: 0 ~ 55°C, Discharge: -20 ~ 55°C, nominal voltage 51.2 V, storage temperature -20 ~ 30°C (12 months), 30 ~ 60°C (6 months), communication CAN / RS485 and cycle life ＞6000 Cycles (25℃ ±2℃, 0.2C / 0.2C, 90%DOD, 70%EOL).

Who makes Fronus TP LD 51 5.12kWh Lithium Ion Battery 51V 100Ah?
Fronus TP LD 51 5.12kWh Lithium Ion Battery 51V 100Ah is a Fronus product, listed under batteries with model reference FROS-40. The Fronus brand page lists the rest of its range so you can compare across the catalogue.
Is Fronus TP LD 51 5.12kWh Lithium Ion Battery 51V 100Ah right for my system?
That depends on what it has to connect to. For a battery, check 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 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 TP LD 51 5.12kWh Lithium Ion Battery 51V 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.
