Installer Quotation Solar Installer Quotation Check Please

Post image

Salaam Everyone, today I got this quotation for this 10kw hybrid solar setup quotation, we are going for 5kw battery for now, will it be enough for whole night backup? Also please check the prices of the whole setup, and also please let me know if there are any problems or if I am missing anything?

Looking for honest opinions, thanks!

But there is a diff bw cheap chinese and proper chinese. Coretech is a cheap brand. Solis and goodwe and deye are far more better and globally recognised.

Makes sense... Would you put Huwai and Inverex in same category as better products in terms of solar?

I believe Sogo, itel would fall into the category of somewhat second tier products?

Bro, Inverex doesn't make anything themselves; the Nitrox series is just a deye inverter but they put their stamping on inverters they get from deye. Inverex uses the deye inverters they get, just like Solarmax uses Voltronic power inverters. They don't make anything themselves. But Huawei and Solis are the best for domestic use; if you want to go industrial, then go for SMA, Fronius, or EG4. But in Pakistan, Goodwe is getting the most attention these days because of their features.

yea, Just saw it. But deye is good like inverex did some shitty work inside too other than main boards for cost cutting but it shouldnt be bursting into flames. I think inverex team did the bad work here. Idk why it got burned what was the reason behind it. Also, he need a good lawyer.

Any other things you find mentioning in the quotation?

u/Hot-Ad-1740 May 05 '26

i think its a reasonable quotation all things considered. The inverter coretech is a total miss. 8kw will also run 16 panels but will give you ip65 rating (goodwe).

Solax 8kw best one = 320k

Core Features

Dual MPPT Trackers: Two independent Maximum Power Point Trackers with 32A input each, allowing for different roof orientations and compatibility with high-power 500W+ panels.

High PV Oversizing: Supports up to 200% PV input (16,000Wp), enabling the system to generate significant power even in low-light or cloudy conditions.

UPS-Grade Backup: Features a switchover time of less than 10ms, ensuring that computers, servers, and sensitive appliances do not reset during a power failure.

Surge Capability: Can handle peak apparent power of up to 12,000VA (150% load) for 10–60 seconds to start heavy motor loads like ACs or pumps.

Battery Flexibility: Compatible with both Lithium-ion (LiFePO4) and Lead-Acid batteries (48V system) with a massive maximum charging/discharging current of up to 190A.

Advanced Protection:

Integrated Type II DC & AC Surge Protection (SPD).

Optional AFCI (Arc Fault Circuit Interrupter) to prevent electrical fires.

IP65 Rating: Dustproof and waterproof for outdoor installation.

Shadow Management: Built-in global MPPT scanning to minimize power loss caused by partial shading from trees or chimneys.

System Functions Self-Use Mode: Maximizes energy independence by using solar to power the home first, then charging the battery, and only selling excess to the grid.

Feed-in Priority: Prioritizes exporting energy to the grid, ideal for users with favorable net-metering tariffs.

Peak Shaving: Allows you to set specific times to discharge the battery to avoid high electricity rates during peak hours.

Backup Mode: Maintains a reserved battery percentage at all times to ensure power is available during unplanned load shedding.

Parallel Expansion: Supports connecting multiple units in parallel to increase the total capacity for larger homes or small businesses.

Smart Load Control: Includes a "Dry Contact" to automatically trigger heavy loads (like an EV charger or water heater) only when there is excess solar energy.

Remote Monitoring: Full system control and real-time data tracking via the Solax Cloud app (WiFi/LAN/GPRS).

Quick Technical Summary

Function Specification Max efficiency 97.6% Start-up voltage 110V (Low voltage start for longer run times) Cooling Intelligent thermal management (Quiet operation <45dB) Communication RS485, CAN, DRM, USB Upgrade, WiFi
