Practical answers for solar power planning.
Use these answers to prepare an EcoSolLi inverter or MPPT controller installation. The product manual and applicable electrical requirements always take priority.
Shipping and delivery
Who handles EcoSolLi shipping?
Amazon handles order processing, shipping and delivery for all current EcoSolLi sales.
How long does delivery take?
Most available products arrive within one to five business days. The destination, inventory and selected service affect the actual date shown at checkout.
Is expedited or international shipping available?
Prime and Amazon Global options appear when supported for the product and delivery address.
Sizing your system
How do I choose the correct inverter size?
Add the continuous wattage of loads that may operate together, identify motor or compressor startup surge and choose an inverter with suitable headroom. Also confirm output voltage and phase requirements.
How do I match a battery bank?
Use the DC voltage required by the inverter and confirm that the battery bank can supply the continuous and surge current. The battery protection system and cabling must be rated for the expected load.
How should I size the solar array?
Keep array open-circuit voltage below the controller maximum in the coldest expected conditions. Stay within the rated MPPT voltage and input-current limits, then size array wattage around local solar conditions and daily energy demand.
Can I expand the system later?
Selected EcoSolLi inverters support parallel operation. Use matching models and follow the manual for cables, communications, phase configuration and maximum unit count.
Installation and operation
Can I install the equipment myself?
Qualified installation is strongly recommended for high-voltage PV input, split phase output and high-current battery systems. Local electrical rules and required disconnects, grounding and overcurrent protection must be followed.
What should I check before power-up?
Verify polarity, cable size, terminal torque, protective devices, grounding, battery voltage and PV open-circuit voltage. Confirm every connection against the manual before energizing the system.
Which charging and output mode should I use?
Choose modes according to whether solar use, battery reserve or utility availability has priority. Record the settings and monitor operation after commissioning.
How does remote monitoring work?
Supported inverter models use WiFi or GPRS connectivity to display operating data. Availability and setup steps vary by model.
Warranty and returns
What warranty does EcoSolLi provide?
EcoSolLi products include a two-year limited warranty covering manufacturing defects under normal use, plus lifetime technical assistance.
How do I start a warranty claim?
Open the purchase in Amazon order history and contact EcoSolLi through Amazon messaging. Include the order number, model, warning code or display readings and a clear description.
What is the return policy?
Unused products in original packaging may be eligible for return within 30 days. Start the request through Amazon order management.
When is a refund processed?
After approval and receipt, refunds are generally processed within one to two business days. The bank or card provider may require additional time.
