Hi....I'm new to the forum, about to pull the trigger on an install for lithium/all-in-one/pv backup.
I'd really appreciate any feedback (warnings) for the system design and components:
The system is to provide residential backup for poor grid supply (frequent random outages and voltage drops) in Africa, near equator.
Daily load = 7.9kWhr (could be cut to 5.5kWhr essential)
Absolute peak load 5.3 kW (very unlikely)
Proposed system:
2 x WECO LiFeO 4.95kWhr
1x Growatt SPF 5000TL HVM-WPV
10 x Suntech STP-330
5kVa backup genset on changeover if required. 220V grid supply when operational - power outages are unpredictable, usually do not last more than 6 hrs, but occasionally [once p.m.] can be 24 hrs or more.
The installer/supplier is offering a 10 year warranty on the WECO batteries, but only 2 years on the Growatt all-in-one..............should I be suspicious? Is this unit prone to problems?
Any other quality/performance issues from members experience?
Is the system sizing in the ball park?
Thanks for this forum!! Awesome stuff
*forgot to mention although it is a grid-tie there is no feed-in to the grid
