What Agriculture & Irrigation Storage Covers
Ministry of Agriculture promotes "solar replaces diesel" policy with increasing subsidies. But core farmer concern: "what about cloudy days?" — crops don't wait, irrigation windows are just days. PLB agricultural: solar + water tower dual buffer + backup interface, ≥98% irrigation guarantee, annual cost drops to ¥3–5/mu, 2–3 year payback.
Professional Battery Solutions
¥5 2~3 Save ¥50,000/Year Irrigation — 2-3 Year Payback
100-mu diesel irrigation: ¥30,000–50,000/year (fuel + labor). Diesel engines frequently break down — field repairs inconvenient, missing irrigation timing = yield loss or total crop failure. Agricultural enterprises calculate clearly: 2–3 year payback + 7 years pure savings — worth investing.
PLB agricultural: 5kW solar + 10kWh storage + pump controller, driving 1.5–3kW submersible pump. Daytime solar direct pumping → water tower → on-demand irrigation. Annual from ¥30,000–50,000 to ¥3,000–5,000 (depreciation). 3-year payback. Compatible with mainstream pumps, AC/DC dual-mode.

+ —— IP67 + Anti-Rodent + Anti-Pesticide — Zero Field Failures
The pain is specific: + —— IP67 + Anti-Rodent + Anti-Pesticide — Zero Field Failures In daily operation, lead-acid or manually managed packs lose capacity between scheduled checks, maintenance teams cannot inspect every unit, and the failure surfaces only when the load is already at risk.
PLB agricultural IP67 fully sealed (brief submersion OK) + corrosion-resistant (pesticide/fertilizer) + anti-rodent steel armored cables. PLB's LiFePO₄ pack and BMS monitor cell voltage, temperature and SOC continuously, alert before a weak cell becomes a failure, and are sized to the application's load profile.

+ —— Water + Energy Dual Buffer — Irrigate Even on Cloudy Days
Biggest solar irrigation concern: "what about cloudy days?" Crops don't wait — missing irrigation windows means yield loss. Pure solar stops on cloudy days, farmers dare not adopt — the biggest barrier to market adoption. Without "cloudy day solution," there's no market.
PLB "solar pumping → water tower → on-demand irrigation" — pump full during sun hours (energy stored as water). 10kWh + 5m³ water tower = 1-2 cloudy days irrigation. Optional diesel/electric backup auto-switches. Irrigation guarantee ≥98%. With this solution, farmers dare to adopt — market opens up.
| Direct solar drive | PLB dual buffer | |
|---|---|---|
| Irrigation through cloudy days | Not possible, direct drive | 1–2 days from the buffer |
| Supply guarantee | About 70% | 98% or more |
| Backup option | None | Diesel or mains backup |
| Farmer acceptance | Low | High |
Solution Advantages
90% Cost Cut
¥3–5/mu → ¥0.3-0.5/mu
Annual irrigation cost drops from ¥30,000–50,000 to ¥3,000–5,000, paying back in two to three years and saving purely thereafter — verified on 100 mu of land.
Verified on 100 mu · ¥25,000–45,000 saved a yearField Tough
IP67, anti-corrosion, anti-rodent
IP67 sealing with agrochemical resistance and a rodent-proof armoured sheath keeps the system fault-free through the whole farming season.
In-house agricultural protection · Five years maintenance-free in the fieldDual Buffer
Water tower + battery, ≥98%
Solar feeds both a water tower and the battery bank, so irrigation continues for one or two days of cloud with a supply guarantee of 98% or more.

Frequently Asked Questions
The questions EPC contractors and off-grid operators ask most about LiFePO₄ off-grid storage in the Agriculture & Irrigation scenario — 2–3 years (payback), and what it takes to qualify.
What has to change on the site before a LiFePO₄ pack goes into the Agriculture & Irrigation scenario?
The storage keeps the site DC bus voltage and stacks in modular units, and the inverter charge settings are documented for commissioning. Typical models for Agriculture & Irrigation builds are LL-OG-AGRI10 and LL-OG-AGRI20.
Does output stay flat through a whole Agriculture & Irrigation day?
Usable depth of discharge is about 90% against roughly 50% for lead-acid, so the same nameplate rating delivers close to twice the usable energy.
How is the pack sealed and thermally managed in Agriculture & Irrigation duty?
The enclosure is rated for outdoor and remote-site duty, with BMS thermal protection and wide-temperature cells.
Is a special charger needed in the Agriculture & Irrigation scenario?
Solar is the primary source and the BMS manages charge acceptance, with generator or grid backup where the site requires it.
What warranty and after-sales support apply in the Agriculture & Irrigation scenario?
Standard products carry a full warranty backed by lifetime technical support, with terms confirmed on the quotation; export packing is UN 38.3-certified with MSDS. Tell us the daily kilowatt-hour demand, peak load and site conditions — our engineers size the system and recommend the matching model within 24 hours.
