Solar Panel
Sail Solar 440W‑740W solar PV modules are high‑efficiency solar panels built for commercial, industrial and utility‑scale solar projects. Powered by advanced cell technology, they offer high power output, superior conversion efficiency and dependable long‑term performance.
Featuring robust mechanical strength, these panels withstand wind, snow and other harsh outdoor conditions, fitting both rooftop and ground‑mount installation scenarios. Covering a broad power spectrum from 440W to 740W, they bring great flexibility for system design. They also help cut balance‑of‑system costs and maximize energy production per square meter.
Inverter
Solution 1: 1× Megarevo Micro‑grid Hybrid Inverter
This solution adopts one‑unit Megarevo industrial micro‑grid hybrid inverter with rated 500kW output power. It integrates MPPT modules, isolation transformer, STS and maintenance bypass inside one single cabinet. It supports 100% three‑phase unbalanced load, diesel generator input and flexible micro‑grid control strategies, well‑suited for weak‑grid, off‑grid and hybrid genset‑grid C&I projects. With wide operating temperature range of ‑30℃~+55℃, it delivers stable performance for harsh site conditions. Single‑unit architecture simplifies system commissioning, reduces parallel‑related coordination risk, and supports further multi‑unit parallel for future capacity expansion.
Solution 2: 4× Solis 125kw Hybrid Inverter Parallel Connection (Total 500kW)
This solution uses four pieces of Solis 125kW high‑voltage hybrid inverters running in parallel to achieve total 500kW rated AC output power. Each unit is IP66 outdoor‑ready with 10 MPPT trackers, dual independent battery ports and Solis Cloud remote AI management platform. It supports <10ms on/off‑grid transfer for each unit and rich grid‑friendly functions including dynamic reactive power compensation, anti‑reverse flow and utility bypass. Modular parallel design allows partial‑capacity operation: if one unit fails, remaining inverters can keep partial system output instead of full system shutdown.
High Voltage Battery
Sail Solar 1000kWh High‑Voltage Lithium Battery System is a reliable, scalable energy‑storage solution tailored for commercial and industrial scenarios. Constructed with high‑performance lithium‑ion cells, it features high energy density, long cycle life and outstanding safety performance.
This battery system uses a high‑voltage design to cut current losses and boost overall system efficiency. The integrated intelligent Battery Management System(BMS provides real‑time status monitoring), cell balancing, as well as multi‑layer protection against over‑charging, over‑discharging, short‑circuit and thermal hazards. its modular structure, the system supports flexible deployment and convenient capacity expansion. It fits perfectly for peak‑valley load shifting, emergency backup power and renewable‑energy integration projects.
Sail Solar 500kW/1000kWh solar energy storage is built for C&I use to realize PV self-consumption, and backup power.
Two optional configurations are available:
one adopts a single 500kW Megarevo hybrid inverter paired with 5 PDUs (13 battery modules per PDU, 65 modules in total), featuring easy commissioning and stable grid-tied/microgrid performance;
the other uses four 125kW Solis hybrid inverters in parallel for a total 500kW power, matched with 4 PDUs (16 battery modules per PDU, 64 modules in total), delivering modular redundancy for higher reliability.
Both versions are equipped with a central control cabinet and high-voltage battery PDUs to monitor and coordinate PV, PCS and battery operation.

FAQ
Q1.What is the difference between Megarevo MPS500 single‑unit and 4‑unit parallel Solis 125kW solutions?
A：Megarevo MPS500 is one‑unit 500kW with built‑in transformer, good for micro‑grid / genset‑hybrid scenarios and supports 100% unbalanced‑load. The 4×Solis parallel solution offers modular redundancy: one‑unit fault will not shut down the whole system, and its IP66 inverters bring flexible installation choices.
Q2：Will the whole system shut down if one inverter fails in 4×Solis 125kW parallel solution？
A：No. Thanks to modular parallel design, the remaining healthy inverters can keep partial power output. However, on‑site re‑commissioning is required for the faulty unit.
Q3：What functions can this 500kW/1000kWh BESS achieve?
A：It supports PV self‑consumption improvement, peak‑valley arbitrage, peak‑load shaving and emergency backup power. Both PCS options support grid‑tied mode; Megarevo MPS500 has stronger native micro‑grid and generator‑hybrid capability.
