A tubular battery uses advanced tubular plate technology to store solar energy. It is designed for deep discharge cycles, making it ideal for areas with frequent power cuts and voltage fluctuations.

Eastman tubular batteries are built for 1,800–3,800 cycles at 80% depth of discharge, delivering reliable backup for years with minimal maintenance.

Eastman tubular batteries have very low water loss — requiring rare top-ups compared to standard batteries, significantly reducing maintenance effort and cost.

Yes. Eastman tubular batteries generate almost no fumes during charging, making them safe to install in homes near living spaces without ventilation concerns.

Eastman tubular batteries support 80% depth of discharge — meaning you can use 80% of the stored capacity before recharging, without affecting battery health or lifespan.

The Regular Series (EM150SB–EM260SB) is a standard tubular battery designed for general solar and backup use. The Solar Smart Series is specifically optimised for solar charging cycles, delivering better performance when paired with solar inverters.

Eastman tubular batteries are compatible with Eastman Solar Off-Grid Inverters (Solar Smart and Solar Prime series) and most standard solar inverter brands.

Eastman tubular batteries deliver 5% more backup than the rated capacity printed on the label — meaning more power at no extra cost.

Tubular batteries require minimal maintenance — periodically check water levels and top up with distilled water when needed. Eastman's low water loss design reduces this need significantly.

Eastman's Regular Series carries up to 20 years warranty (10 Years Replacement + 10 Years Pro-Rata) and the Solar Smart Series carries 72 months warranty (36 Months Replacement + 36 Months Pro-Rata).

A lithium battery uses LiFePO₄ chemistry for energy storage. Compared to tubular batteries, it is lighter, charges faster, lasts 3x longer in cycle life, requires zero maintenance and has no fumes or water top-up needs.

LiFePO₄ (Lithium Iron Phosphate) is the safest and most stable lithium chemistry for solar energy storage. It offers high cycle life, excellent thermal stability, zero toxic emissions and consistent performance across temperature ranges.

Eastman lithium batteries support up to 80% DoD — meaning you can use 80% of the stored capacity without affecting battery health or lifespan, delivering more usable energy per charge.

Yes. Eastman Wall Mounted LiFePO₄ batteries can be connected in parallel up to 15 units — allowing you to scale storage capacity as your energy needs grow, without replacing existing equipment.

A BMS is a built-in protection system that monitors and manages battery charging, discharging, temperature and cell balancing. Eastman lithium batteries come with a Smart BMS for safe and efficient operation.

Wall Mounted batteries are compact and designed for residential use (51.2V, 100Ah & 150Ah). Rack Type batteries are modular, high-capacity units for commercial installations (51.2V, 100Ah). LFP batteries cover a wider voltage and capacity range (25.6V–51.2V, 100Ah–280Ah) for diverse solar applications.

No. Unlike tubular batteries, lithium batteries require zero maintenance — no water top-ups, no servicing and no periodic checks. The built-in Smart BMS handles all health monitoring automatically.

Eastman lithium batteries can be monitored via the Eastman iConnect App — track charge levels, health, power flow and performance in real time from your smartphone.

Yes. Eastman LiFePO₄ batteries are the safest lithium chemistry — they produce zero fumes, have no risk of thermal runaway under normal operating conditions and are fully safe for residential indoor installation.

Eastman Wall Mounted and Rack Type LiFePO₄ batteries carry a 10-year warranty. The LFP range (25.6V–51.2V) carries a 5-year warranty. All batteries are backed by Eastman Assure service support.

DCR (Domestic Content Requirement) panels are manufactured with Indian-made solar cells and qualify for PM Surya Ghar Muft Bijli Yojana subsidies. NON-DCR panels use imported cells and are not eligible for residential government subsidies.

A monocrystalline panel is made from a single crystal structure, offering higher efficiency and better performance in low-light conditions compared to polycrystalline panels. All Eastman solar panels use monocrystalline cell technology.

A bifacial panel captures sunlight from both front and rear surfaces — boosting energy generation by harvesting reflected light. It is ideal for open rooftops, elevated mounting structures and ground-mount systems where the rear surface receives reflected light.

TOPCon (Tunnel Oxide Passivated Contact) is a next-generation cell technology that delivers higher efficiency, lower degradation and better performance in low-light and high-temperature conditions compared to standard monocrystalline panels.

Module efficiency is the percentage of sunlight converted into electricity. Eastman panels offer 22–25%+ module efficiency — meaning more power generated from the same roof space, making your solar system more cost-effective per square foot.

Yes. All Eastman DCR solar panels are BIS and ALMM certified — fully compliant with Indian quality standards and eligible for PM Surya Ghar Muft Bijli Yojana subsidies and government incentives.

Eastman solar panels are backed by a product warranty of up to 30 years for TOPCon variants and 27 years for bifacial variants. They are built to deliver consistent performance with minimal degradation over decades.

PID (Potential Induced Degradation) resistance prevents efficiency loss caused by voltage stress over time. Eastman solar panels are PID resistant, ensuring long-term durability even in challenging humidity and temperature conditions.

Yes. Eastman solar panels feature a durable glass and frame structure with strong mechanical load capacity — designed to handle high winds, heavy rains, extreme heat and physical stress common in Indian weather conditions.

Yes — Eastman's DCR solar panels (EBP550W, ETC TOPCON 600W, ETC TOPCON 635W) qualify for up to ₹78,000 central government subsidy + additional state subsidy under PM Surya Ghar Muft Bijli Yojana for residential rooftop installations.

A BOS kit contains all the essential components needed for a safe, compliant and professional solar installation — except the solar panels, inverter and cables. It includes protection equipment, earthing components and installation accessories.

The BOS Without Cable kit is a comprehensive 19-component kit covering AC/DC protection, earthing, surge protection and all installation accessories. The ACDB/DCDB kit is a focused 7-component kit covering only the core safety and earthing components for installers who already have other accessories.

Proper earthing protects your solar system and home from lightning surges and fault currents. Eastman's BOS kit includes copper-bounded earthing rods, bentonite chemical bags and earth pit covers for complete earthing protection as per Indian installation standards.

Both BOS kits include a Type II Lightning Arrester and MC4 connectors rated at 1000V DC — protecting your system from sudden voltage spikes from both the solar side and grid side without needing any extra device.

MC4 connectors are weatherproof solar-grade connectors used to connect solar panels to the inverter. Eastman's BOS kit includes 1000V DC rated MC4 connectors — ensuring safe, secure and efficient DC-side panel wiring.

ACDB (AC Distribution Box) protects the AC output side of the inverter from overloads and faults. DCDB (DC Distribution Box) protects the DC input side from panel strings. Both are included in Eastman's BOS kit for complete system protection.

Yes. Eastman's BOS kits are designed for On-Grid Solar installations (Single Phase, 1P1M) and are compatible with all standard solar inverter brands and panel configurations.

PU (Polyurethane) foam is a waterproof sealant used to seal cable entry points, conduit gaps and mounting holes — preventing water ingress and ensuring a weather-tight, professionally finished solar installation.

Bentonite is a natural earthing compound used to enhance soil conductivity around earthing rods — ensuring effective grounding of the solar system as per safety standards. Eastman's kit includes 24 kg bentonite for complete earthing compliance.

The BOS Without Cable kit covers everything except cables, solar panels and the inverter. The ACDB/DCDB kit covers only safety and earthing components. For a complete installation, you will additionally need DC solar cables, AC power cables and your choice of Eastman inverter and solar panels.
